[HELP] Is my hardware really not supported?

CPU: AMD Ryzen 7 3800XT

GPU: Nvidia RTX 2070 Super

Mobo: B550-F

Guide:

Following this guide, haven't started yet but it looks like my GPU hardware is not supported? Since my AMD chip does not have integrated graphics its not possible for me to run a hackintosh setup with this hardware?

I saw here that Turing GPUs are actually supported in 10.13 High Sierra? Does this mean that my hardware is actually supported for High Sierra?

Just wanted to confirm if my hardware is really not supported and figure out what my options are.

Thanks!
