That’s how I’m doing until now (use update CD), and one of the reason I’m sticking with ThinkPads.
But what I really want is that UEFI firmware to have config option for updating itself using (bare or compressed) firmware image file in somewhere in the ESP (for example, in FIRMWARE directory) by validating singature, check whether it matches current one or not, and if differes (new or old), configure itself to go into actual up(down)grading mode on next boot and reboot.
In this case, putting “updater UEFI executable” there SHALL not be an option to avoid malwares. SHALL be the image itself (bare or purely compressed by any method the current firmware supports and can validate).
