What a ridiculously bad idea. :-/
As an anecdote, MSI's dragon center utility bricked my motherboard trying to apply a BIOS/UEFI update which required me to use the flashback recovery method and wait in terror for about 15 minutes to see if I would have a working computer again.
After that experience, I will only use the usb thumb drive + booting into BIOS/UEFI method for applying updates.
