Need to remove comments feed URL for my site like: https://mysite/comment/feed/

Hello,

I need to remove: /comment/feed/ – this URL of my site. https://123.demowebsites.club/comment/feed/ – this URL.
For that, I added code in function.php. But it is only disabled in the header.

So please give a solution for how I delete or remove this URL for my site. Meance when I paste this URL in the browser I want that URL gives 404 not found in my site, not an XML file of comment/feed.
It is urgent. So please give proper solution for that.

Waiting for your response.

Thank You.
