Tahoe allows you to disable menu items, but AFAIK then they are fully unavailable. There is no way to stuff them into an overflow area and bring them back up on-demand. That's what I use Ice for, to stick infrequently accessed ones into a spot where they aren't taking up space on the screen but I can get to them if I need to.I only used it to hide certain menu extras I couldn’t disable. macOS Tahoe offers that natively now.
(If Tahoe does have this functionality, I'd love to hear about it...)
