On the forum home page, how do I hide categories?

hey,

On the forum home page, how do I hide categories?
Do you have any way to hide the categories and boards from being displayed on the homepage?
Could there be a plugin that displays forum posts on the home page of my website.based on category blocks (for example, if my forum is at example.com/forum, and I want to display posts on different blocks based on forum categories/boards just as blog posts are displayed on home page based on categories).
Can social media login be done with a plugin? This is a popular demand, so please address it if no).
