To upgrade the UEFI or other hardware-level firmware you need a way to upgrade. Best OEMs use LFVS; good OEMs use have ISOs or bin files you can flash from UEFI; terrible OEMs lock that into a Windows-only executable.
In my case there was a fan & thermal update I was never able to get.
I still want to know if MQTT already did this & UnifiedPush is just a startup trying to reimplement the same concept
