I am not a DT or u-boot developer but I observe these things:

1) DT include for a SoC has all supported devices. Some which require
external parts (eg. physical connectors, extra PHY, ...) are listed as
disabled and particular board DT enables them.

2) there is code for setting mac address on ethernet nodes with a
specific alias so you could perhaps reuse this code to set disabled
option on particular nodes.

Thanks
