Some friendly tips from post-silicon validation:
sudo systemctl reboot --firmware
shutdown /r /t 0 /fw
These reboot directly into BIOS.
For Windows CMD+R menu, run it by pressing CTRL+SHIFT+Enter (elevates to admin). You may have to do it twice for some unknown reasons after reinstalling the OS.
Had to learn this recently when my wife’s computer refused to register requests to boot into bios despite spamming F12 / Del many different times across many different USB ports. Such a pain in the ass.
You are a life saver. I never knew about --firmware!
