Big Sur - How do I disable the control center or control it fully?

If that's a dealbreaker you'll be heading back to Linux. You can't disable the Control Centre and there are some modules that cannot be removed.

On the upside, while I did find it irritating at first, it was only when I saw your post that I even remembered it.

As Others more experienced have already mentioned. If one really does not like the feature - suggest directing complaints directly to Apple via Feedback. Apple controls the OS. We are only fellow Apple Users like yourself.

Use Control Center on Mac

It is not possible to remove it or to change the layout. You can just move controls between the main menu bar and the Control Center. I simply ignore it like Yer_Man wrote. I enabled "Show in Menu Bar" and "Menu Bar Only" (if available) in System Preferences > Dock & Menu Bar, for all items, that I ever need to use, so I never have to look at the Control Center again, as the menu bar is always available.

If this is one of the first things that Apple "forces" upon you, who knows what more will come.

Might be best to have a little bit of perspective on this. It's not like you're "forced" under threat of pain and torture. It's a feature - one of hundreds - that I have no use for. Everything it does I can do faster and more easily from the keyboard. So, after a bit, I forgot about it. Similarly, even though I've been using Macs for just short of thirty years now, I have never once used Screen Mirroring. But that's not a reason to try find an OS that doesn't have it. I just forget about it.

The Mac OS has never been as configurable as Linux, and for an awful lot of Mac users that's a good thing.

Sorry, I forgot your new name. 🤭
