In the past, some code was introduced on the B&R automation to take some actions in case the UEFI nodes had a certain boot configuration. Since then, it was verified that the boot configuration was not related at all with how OpenStack manages UEFI, but it was an error on the physical installation of the OS. That code does nothing so it needs to be cleaned up.
