Vendor\Extension\etc\adminhtml\system.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
  <system>
    <section id="mymodule" sortOrder="150" type="text" showInDefault="1" showInWebsite="1" showInStore="1">
      <label>Mymodule Label</label>
      <tab>mymoduletab</tab>
      <resource>Module_First::mymodule_configuration</resource>
      <group id="general" translate="label" sortOrder="10" type="text" showInDefault="1" showInWebsite="1" showInStore="1">
        <label>General Configuration</label>
        <field id="enable" translate="label" sortOrder="10" type="select" showInDefault="1" showInWebsite="1" showInStore="1">
          <label>Enable</label>
          <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
        </field>
      </group>
    </section>
  </system>
</config>

And to check that field value in phtml you can create Helper file (Data.php) at this location Vendor/Extension/Helper/Data.php.

<?php
namespace Vendor\Extension\Helper;

use Magento\Framework\App\Helper\AbstractHelper;
use Magento\Framework\App\Helper\Context;
use Magento\Store\Model\ScopeInterface;

class Data extends AbstractHelper
{
    protected $context;

    public function __construct(Context $context)
    {
        $this->context = $context;
        parent::__construct($context);
    }

    public function isEnable()
    {
        return $this->scopeConfig->getValue('mymodule/general/enable', ScopeInterface::SCOPE_STORE);
    }
}

Now Write this code in phtml file :

<?php 
$helper = \Magento\Framework\App\ObjectManager::getInstance()->get('Vendor\Extension\Helper\Data'); 
if($helper->isEnable()) : ?>

//WRITE YOUR CODE HERE

<?php endif; ?>

system.xml file

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <system>
        <tab id="mytab" translate="custom Configuration" sortOrder="100" class="trademe-extensions-tab">
            <label>Custom Customer Attribute</label>
        </tab>
        <section id="custom_module" translate="TradeMe Settings" sortOrder="130" showInDefault="1" showInWebsite="1" showInStore="1">
            <class>separator-top</class>
            <label>Custom Customer Attribute</label>
            <tab>mytab</tab>
            <resource>Eecom_CustomCustomerAttribute::custom_module</resource>
            <group id="general" translate="TradeMe Configuration" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>General Configuration</label>
                <field id="enable" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
                    <label>Enable Module</label>
                    <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
                </field> 
        </group>
  </section>
</system>
</config>

Controller file

protected $scopeConfig;

const CUSTOM_MODULE_ENABLE = 'custom_module/general/enable';

public function __construct(
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
) {
    $this->scopeConfig = $scopeConfig;
}

public function execute()
{
    echo $isEnable  = $this->scopeConfig->getValue(self::CUSTOM_MODULE_ENABLE, \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
}

Answer 3

Your Helper File replace by this code

<?php

namespace Eecom\CustomCustomerAttribute\Helper;

use Magento\Store\Model\ScopeInterface;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{

    const MODULE_ENABLE_DISABLE = 'custom_module/general/enable'; // SectionName/GroupName/FieldNAme from system.xml

    public function __construct(
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    ) {
        $this->scopeConfig = $scopeConfig;
    }

    public function setStoreScope()
    {
        return ScopeInterface::SCOPE_STORE;
    }
    public function isEnabled()
    {
        return $this->scopeConfig->getValue(static::MODULE_ENABLE_DISABLE, $this->setStoreScope());
    }
}

Note: module is not directly enable or disable from system.xml to field. we are provide admin can easily interact with our module our module provide more flexibility using system.xml

I would prefer to disable the module via terminal

bin/magento module:disable ${MODULE_NAME}

If it says there is no such module, try listing all enabled ones to find yours

bin/magento module:status --enabled
