How to hide specific subforums on forumhome?

On a vB 3.7.x forum, I want to hide specific subforums.

The few topics at vB.com are for vB 3.6 and earlier and don't work on vB 3.7 -3.8
The few topics at vB.org have mostly gone unanswered. The one Cyb plugin that would give this ability also offers more than I need, plus there's reports it conflicts with vBSEO (and that's not good).
So I thought I'd try here...

Is there any way to hide specific subforums on the forumhome, in vB 3.7 or vB 3.8 ?

Template edits preferred.
Plugin if that's all it does -- i.e., lightweight minimalist plugin. (I don't want it to interfere with vBSEO.)

Lately it seems this is best place for asking general vB questions.
Thanks.

This is not a vbseo feature. You'll likely have better results at vb.org.

I ended up figuring it out. I'll have to write it up and share sometime.

Thanks for replying.
