InstallData.php

<?php
namespace Vendor\Module\Setup;

use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{

        $setup->startSetup();

        if (version_compare($context->getVersion(), '0.0.1', '<=')) {

            $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

                $eavSetup->addAttribute(

                            'label'    => 'Display Category in Homepage',
                            'input'    => 'Boolean',

                        ]
                );
        }

        $setup->endSetup();

Try to get value from it like this

<?php

namespace Vendor\Module\Block;

use Magento\Catalog\Model\Product;

class Categoryimage extends \Magento\Framework\View\Element\Template
{
    protected $_categoryFactory;

    protected $_storeManager;

    protected $_categoryNameFactory;

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Catalog\Model\CategoryFactory $categoryNameFactory,
        \Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $collecionFactory,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Framework\Registry $registry,
        array $data = []
    )
    {
        $this->_coreRegistry = $registry;
        $this->_categoryNameFactory = $categoryNameFactory;
        $this->_categoryFactory = $collecionFactory;
        $this->_storeManager = $storeManager;
        parent::__construct($context, $data);
    }

    public function getEnableCategory()
    {
        // this return all category with enable attribute values
        $category = $this->_categoryFactory->create()->addAttributeToFilter('is_enable_attribute11',1)->setStore($this->_storeManager->getStore());
        return $category;
    }

    public function getCategoryName($categoryId)
    {
        $category = $this->_categoryNameFactory->create()->load($categoryId)->setStore($this->_storeManager->getStore());
        //$categoryName = $category->getName();
        return $category;
    }
}

Also try this to get values from collection

$category->getMyCustomAttribute()
// or
$category->getData('my_custom_attribute');
// or
$category->addAttributeToSelect('my_custom_attribute')

Add the Below code in your block class

<?php 
    
 namespace Vendor\Module\Block;

 use Magento\Framework\View\Element\Template;

  class CategoryCollection extends \Magento\Framework\View\Element\Template{
       
    protected $categoryRepository;

    public function __construct(
        Template\Context $context,
        \Magento\Catalog\Model\CategoryRepository $categoryRepository,
        array $data = []
    )

    {
        $this->categoryRepository = $categoryRepository;
        parent::__construct($context, $data);
    }

    public function getCategoryAttribute($id){
        return $this->categoryRepository->get($id);
    }
     
  }

Add the Below Code in your phtml file

<?php

    /**
     *
     * @var $block \vendor\Module\Block\CategoryCollection 
     */
     
  $id = 10; //your category id.
  
    
 $customAttribute= $block->getCategoryAttribute($id);
 echo $customAttribute->getData('attribute_code');

?>
