Yesterday I had to open up a huge ass PC case and disconnect GPU to be able to physically remove 2nd SSD drive, so that Windows 11 could perform a clean install. Simple setup on a modern PC. That's the only solution that worked - found it on reddit as the most upvoted answer. Never had to remove any hardware in order to install Linux. Ofc it's just a stupid anecdote but that's all the quote you posted is based on.
