Extension to disable the display of topics in a category from an extension to recent posts

[LEVI HAVIV]

Hello,

I hope the title is correct and understandable, but anyway my question is this:
If there is a possibility that a certain category when they write in it, the post will not be found in 'Recent Posts' or 'Unread', but still those who have a direct link to the topic / post, can enter and see.

Thank you so much to all the helpers in this precious forum!
