Someone correct me, but being in a similar boat, I think it's Sierra to High Sierra with old EFI Graphics card, which does one firmware upgrade, then swap graphics cards to a new metal-supported card, then do high sierra to mojave, which has another firmware upgrade involved.

I don't know. I installed my metal card and then upgraded to High Sierra and then upgraded to Mojave. I only had 1 firmware upgrade. I'm running a GTX680 2Gb.
