Ask HN: Ist there a way to automate BIOS Upgrade / Blancco

Hi, I got a massive amount of HP Workstations, when u set the BIOS to defaults it enables secure boot.

1. Can I automate the process of flashing the latest BIOS and after that boot from USB Blancco based on Linux.

I just want to know if it's possible to flash BIOS and boot from USB stick after that without having to mess around with Legacy and Secure Boot.

Any help appreciated.
