For anyone who was experiencing this same issue, since upgrading my M1 Ultra Mac Studio to MacOS 27 Golden Gate, my M1 Studio no longer boots into recovery mode and no longer makes the strange 'chirp' sound I referenced in the archived post. Whatever code Apple has changed in MacOS 27 seems to have solved this problem for me. I just successfully updated to 27.0.1 as well without my machine going into recovery mode. Only took 4 years and 5 major OS updates but at least they got it done!
