However, the change is not persistent, and the system starts with the old config (network first), which is also stored in the DefaultBootOrder variable.
The change of the next boot via efibootmgr works fine and we can also change the boot order, and the DefaultBootOrder, persistent within EFI/via BMC.
Since I did not find the DefaultBootOrder in the UEFI specifications[1], I'm unsure if that is the correct approach/variable.

We have some Inspur NF5280R6 systems and are trying to change the boot order via efibootmgr from first from the network to first from disk.
However, the change is not persistent, and the system starts with the old config (network first), which is also stored in the DefaultBootOrder variable.
