BuddyPress and bbPress fullwidth pages

In my quest to make my buddypress pages and bbpress pages in Aegaeus full width, I have found ZERO information anywhere. I would just assume they’re unsupported, but bbpress apppears to be working fine on this site.

It’s funny how nobody seems to have asked this question, or at least that I can find. Surely I can’t be the only one out of thousands of customers who wants full width bbpress/buddypress? I know how to make pages full width from the page editor, there’s a toggle. But that toggle doesn’t exist when attempting to edit forum/buddypress pages. I can’t even find a full width template that I can just rename and copy.

How do I do this??
