I once had an onboard NIC go bad, and the PCI NIC I substituted for it
wouldn't work unless the onboard NIC was disabled. So disabling
onboard hardware may or may not be a net positive.

So long as there are no drivers available for the onboard NIC, it
won't show up in the net subsystem, so udev won't tie it in under net
rules.
