You can use controller_action_predispatch_catalog_product_view event to redirect user to 404 or home page.

In your custom module create

Vendor/MyModule/etc/frontend/etc.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="controller_action_predispatch_catalog_product_view">
        <observer name="custom_pdp_redirect" instance="Vendor\MyModule\Observer\Predispatch"/>
    </event>
</config>

Vendor/MyModule/Observer/Predispatch.php

<?php
namespace Vendor\MyModule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class Predispatch implements ObserverInterface
{

    protected $_redirect;
    protected $_storeManager;
    protected $_url;

    public function __construct(
        \Magento\Framework\App\Response\Http $redirect,
        \Magento\Framework\UrlInterface $url,
        \Magento\Store\Model\StoreManagerInterface $storeManager
    )
    {
        $this->_redirect = $redirect;
        $this->_storeManager = $storeManager;
        $this->_url = $url;
    }

    public function execute(Observer $observer)
    {
        // To redirect to home page
        $homePageUrl  = $this->_storeManager->getStore()->getBaseUrl();
        $this->_redirect->setRedirect($homePageUrl, 301);

        // To redirect to 404 page
        $norouteUrl = $this->_url->getUrl('noroute');
        $this->_redirect->setRedirect($norouteUrl, 301);
    }
}

Thanks!
