No, i use PXE images for that. Doesn't have a modern server IPMI and does the
flash via ipmi bios image upload?

No matter what OS runs for those tools - we still need to kickstart them.

This is the responsiblity of the hardware manufacturer. Btw, let's look on the
uefi shell. It can read partitions and filesystems and load/start software
from. Do you remember toms root boot on a floppy disk? Basically it does the
same. The uefi shell is not a shell of the bios - it's an operating system. If
the flash tool is efi software the efi shell OS could be placed on the USB
stick too. And again, the only job of the BIOS (remember it's BASIC IO) is to
kickstart the boot sequence for an OS.

Which common cases on uefi systems do break the boot process?
