Cannot disable frontend plugin "product_identities_extender"

Question

I wanted to disable the frontend plugin "product_identities_extender" from the module ConfigurableProduct, because this plugin generates too big headers for apache servers. Which results in the known issue Magento 2.3.1 - Issue with catalog search when using php7.2-fpm

I tried to add a module /MyVendor/MyModule to not overwrite Magento core code. In /etc/frontend/di.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Model\Product">
        <plugin name="product_identities_extender" disabled="true"/>
    </type>
</config>

I'm not sure why the plugin wasn't disabled. Do I need something else to disable a Magento plugin?

Make module depended to Magento_Catalog at module.xml
