Such solutions usually include a barcode reader attached to some PC
which is used when you commission the board. And yes, in this case
it is mandatory that the MAC address(es) stored in the environment
(which gets initialized as part of the aforementioned commissioning
procedure) takes precedence over any MAC address(es) that might be
stored somewhere in the hardware.

Right, this is another of a list of reasons why changing the MAC
address makes a lot of sense.
