That is fine. I can PXE boot from the 1GBE port. But then I want to instruct the FreeBSD kernel to use the 10GBE port which does not support PXE booting.

So... You watch the PXE requests to determine what UUID PXE config file (or MAC based PXE config file) is being requested. Then construct a file similar to the stock file you use for all the other systems, labeled to match the request. BUT the image/FreeBSD configs IT provides instruct the booted system to use the interfaces that match your requirements. I haven't done a FreeBSD PXE config in a long while, so I have to leave the exact details of that to you, but that's where the magic happens.
