If you mean HP EliteBooks, it doesn't have to be any more complicated than 1) extract BIOS archive 2) drag & drop BIOS file 3) reboot.
You download the BIOS update .exe, run 7zip on it, and take the BIOS.BIN file and either stick it in the root of your EFI partition and it will install automatically on boot, or just run `fwupdtool install-blob BIOS.BIN` and it will install automatically on reboot.
