We solved that for PC Engines APU2 SeaBIOS some time ago. IIRC What you 
have to do is not run init_optionrom in optionroms.c for iPXE. This not 
run option rom at boot but makes it still visible in SeaBIOS menu. We 
have external switch to enable/disable that behavior.

I believe this was the change:
