Unlike most of HN I am not a "computer person". I know not to click on suspicious links and that's about all that can be said of me. So I'm not sure if you're giving me a hint, or doing the equivalent of telling me to delete System32!
They explained how to trick HP laptops with hard-coded EFI paths into booting Ubuntu anyway. This will overwrite the Windows EFI, so only try this at home if you know what you are doing.
So you can't install Linux at all on HPs post-2020?
