What use-case are you trying to solve with a forced pci enumeration?
With standard boot Ethernet should be enabled when it is needed.
However for EFI boot Ethernet maybe is not detected? Please see [1] for a possible alternative patch that I created when someone reported an issue with iPXE boot some time ago.
I did not get confirmation it fully solved the issue, from what I could test it should help get Ethernet detected during EFI boot on a ROCK 5B.
