       $response = $layout->setData(array("customer_data" => $result))->setTemplate('Vendor_Module::test.phtml')->toHtml();

Answer 1

Please use this

<?php echo $block->getLayout()->createBlock("Magento\Framework\View\Element\Template")->setTemplate('Vendor_Module::test.phtml')->toHtml(); ?>

For Ex. if you call helper function from controller, then you can call PHTML and get data using following way :

/app/code/Vendor/Module/Controller/Index/Index.php

<?php

namespace Vendor\Module\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action
{
    /**
     * @var \Magento\Framework\App\Request\Http
     */
    protected $request;

    /**
     * @var \Vendor\Module\Helper\Data
     */
    protected $helperData;

    /**
     * [__construct description]
     * @param \Magento\Framework\App\Request\Http   $request    [description]
     * @param \Magento\Framework\App\Action\Context $context    [description]
     * @param \Vendor\Module\Helper\Data            $helperData [description]
     */
    public function __construct(
        \Magento\Framework\App\Request\Http $request,
        \Magento\Framework\App\Action\Context $context,
        \Vendor\Module\Helper\Data $helperData
    ) {
        $this->request = $request;
        $this->helperData = $helperData;
        parent::__construct($context);
    }

    public function execute()
    {
        return $this->helperData->getPhtml();
    }
}

/app/code/Vendor/Module/Helper/Data.php

<?php

namespace Vendor\Module\Helper;

use Magento\Framework\View\Result\PageFactory;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
    /**
     * @var \Magento\Framework\Registry
     */
    protected $registry;

    /**
     * @var \Magento\Framework\View\Result\PageFactory
     */
    protected $resultPageFactory;

    /**
     * [__construct description]
     * @param \Magento\Framework\Registry $registry          [description]
     * @param PageFactory                 $resultPageFactory [description]
     */
    public function __construct(
        \Magento\Framework\Registry $registry,
        PageFactory $resultPageFactory

    ) {
        $this->registry = $registry;
        $this->resultPageFactory = $resultPageFactory;
    }

    public function getPhtml()
    {
        $resultPage = $this->resultPageFactory->create();
        $block = $resultPage->getLayout()
            ->createBlock('Magento\Framework\View\Element\Template')
            ->setTemplate('Vendor_Module::test.phtml')
            ->toHtml();
        print_r($block);
    }
}

/app/code/Vendor/Module/view/frontend/templates/test.phtml

<?= "PHTML file"; ?>

I hope it will helpful for you.

You can try,

<?php echo $block->getLayout()->createBlock("Magento\Framework\View\Element\Template")->setTemplate('Vendor_Module::test.phtml')->toHtml(); ?>
