AMD have recently changed the firmware loading signature verification method to apply cpu microcode that uses the on-motherboard tooling. Using the method you talk about would mean that this kind of update wouldnt be possible, 99% of users would never toggle with a switch to update firmware. This would be a huge burden in the server world too, to unrack flip switch, update, revert switch re-install. I assume you mean specifically motherboard firmware updates, because firmware updates are actually pretty common, for most server grade motherboards vendors ship updates about every other month[1]. 1. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git https://git.kernel.org/pub/scm/linux/kernel/git/firmware/lin...
