We don't presently have a user controlled method for limiting what forums you see or have access to in the main message board view.
What we do have is a behind the scenes method to exclude access to the Opinion and Politics, and the Covid 19 boards.
These two are usually the forums that garner the most 'robust' debates, and we know that some folks have little desire to participate in these debates, so the option is available.  
Please let one of the mods or admin know - you can use the private message function for this, or reply to this post...
