Do your panels have any PLC logic to do intelligent load shedding/switching, or is it just the ATS? Sounds like no
One thing you could do is manually switch all the loads off BUT the firepump and emergency lighting on the emergency switchboard, such that you can use the generator to power other loads, but only if manually switched. Kirk-key can enforce this, if you're worried about them "cheating" and only allow them to unlock the breakers when the ATS has switched to generators.
