Is there a way to change and hide the RSS Feed permalink?

Look at this article: https://digwp.com/2012/10/customizing-wordpress-feeds/ for details on how WP does feeds.

Scroll down to the “Customizing feeds with filters and hooks” section for a list of hooks to use for various functions. Lots of good info in that article.

Once you figure out what you want to modify, place the appropriate functions in your Child Theme’s functions.php file. (It is not recommended to modify your theme’s function.php file, as any changes you make will get overwritten on the next theme update.)
