NootRX and 6700xt

i recently bought a powercolor hellhound rx 6700xt as i believed (at the time) that NootRX would allow me to run it in my hackintosh build with no issues other than DRM content, i managed to get it for cheaper than any of the other navi GPUs, and Im trying to get as many components as possible to fit my white colour scheme (so i would really like to keep it if possible).

i was planning on combining it with an aorus z790 elite motherboard and i9 12900kf CPU, but i have realised i may run in to a problem, as NootRX can not be enabled during install, and with the lack of iGPU in the 12900kf i believe (or at least worry) that i will not be able to get graphics output to actually install mac os. Even if I got the non-f model, it’s my understanding that UHD 770 iGPUs are not supported either and wouldn’t solve the issue. (if my fears are wrong please let me know and ignore the rest of the post lol)

i wasn’t planning on installing windows before mac os, but if that is somehow a solution or makes things easier i will.

my questions are:

firstly, are my assumptions about no graphics output during install with this setup correct, and if so, is there any workaround or way to complete the install process without graphics output?

secondly, in the worst case scenario that i just can’t install mac os with this combination, what is the best solution?

i initially thought buying a cheap polaris series GPU like the rx 550 just for install then swapping out could be a possibility, but i realise its likely i would have to change the EFI and reinstall mac os to accommodate the different GPU and that would land me back at square one.

Do I have to just get a CPU with a supported iGPU instead? if i got an older cheap model and spoofed it to 10th gen (if possible), would swapping in the 12900kf and also spoofing to 10th gen be as simple as plug and play?
