I have a laptop from 2k15 with Arch and secure boot. Since Arch doesn't have anything signed you can't even load the LiveISO without disabling secure boot, but what I was able to do was to sign everything myself + have the MS secure boot keys (or whatever they are called). This would allow me to dual boot with Win + Linux both using secure boot, which is nice to know for a certain game that insist on an overly restrictive anti-cheat.
