Believe it or not, it's actually easier to handle on linux than it is on windows now [1]. Normal caveats apply, it depends on your HW manufacturer. However, a lot of them are participating which makes it pretty slick.
replyAnd, assuming your are doing x86, you probably already have an EFI partition so even doing motherboard bios updates isn't much of a big deal. You just drop the update in the FAT32 EFI partition, reboot, and point the motherboard at that location. Some motherboards even support just doing that as part of an online update.
For a hot moment Windows would just update firmware for big vendors as an update. Worked slick. I think vendors are bailing out on this though.
replyThat said some Linux distros can do the same now though I've used so many the last few months I don't know which.
All the distros that support it use the same system, fwupd: https://fwupd.org/
replyIt's the same tool the person you were replying to was pointing at via the Arch wiki. It's pretty standard. I'd expect most distros to support it by now.
