UEFI Update from linux instead of EFI Shell

Farril

Hello,

is there a way to push an UEFI bios update from linux (i.e. ubuntu 22.04 LTS) instead of EFI shell?

We tested the BIOS update process with the EFI Shell and an startup.nsh to automatically update the bios from an USB stick. This requires physical access and manual inputs to the board.

We do not have physical access to the boards and can not plug in an USB memory stick and go through the bios boot selection menu at the customers place and need to update the bios on those systems.

Thanks in advance,
Farril
