I'm curious. Has there ever been an x86 laptop on which secure boot can't be turned off? The most obnoxious I've encountered took quite a few steps, from an obscure key combination to even get into the setup menu, to a couple of "are you sure?", "enter these digits to confirm" kind of scare prompts, to at least one restart, before it was off. Felt kind of like unlocking a carrier-locked smartphone. Pain in the ass and a bit scary, but ultimately possible, and once it's done, for good. After that a Linux install went just fine. Probably would have even without that, given what I read about trusted boot shims and so on. Mind you, all my (older) laptops still support proper suspend, you know, where the LED will happily blink for a couple of days on battery and you still have enough to use the computer.
