      What were you trying to do that didn't work?

      Building a image mode system from kickstart ostreecontainer in UEFI booting host.

      login the system and run efibootmgr failed with "EFI variables are not supported on this system"

      In beaker lab, if I submit a job on r760 x86_64 system with image mode job, it will let the next job abort. That's why I need change boot order on running system. E.g

      ostreecontainer --url images.paas.redhat.com/mhou/rhel-9:rhel-9.6.0-updates-20250811.3-x86_64-stock-1754992233147
      https://beaker.engineering.redhat.com/jobs/11561640 --pass 

      Then I clone above job and re-run failed.
