Remove all favicons from the HTML head.
Out of the box, Magento allows you to define a custom favicon, otherwise it uses Magento's default favicon. Sometimes, a favicon isn't desired at all. This module just removes all favicons, default or otherwise.
composer require markshust/magento2-module-removefavicon
bin/magento module:enable MarkShust_RemoveFavicon
bin/magento setup:upgrade
This module has no configuration. Just install, and you won't see favicons anymore.
