From what I recall last I looked into this, that's technically true but there were a couple gotchas. I can't remember exactly but it was either that it's a major PITA to setup during install (deeply buried in a very non-obvious location), or else that you had to use a MS account to install, but once installed you could then make and use a local account. In either case it's very clear MS is doing everything they can to force you into using their online accounts. I wouldn't be surprised if they remove the ability to activate Windows 11 without using a MS account soon if they haven't already.
