For anyone wondering, there are a few ways to install Windows 11 without creating a Microsoft account.
Probably the simplest — and one that I tested when I needed to do that — was just to give an invalid e-mail address when "creating" that Microsoft account; "elon@test.example" works well, because "example." is a well-known TLD that will never work, so the e-mail is guaranteed to be invalid.
Of course then the problem is that you still end up with Windows 11.
