question about RX 570 on HS

Hi guys,

I have a simple question at the moment - Should I be able to boot into High Sierra with RX 570 without WhateverGreen.kext? Because I am not and I think it is causing me a problems. I was trying to completely shut my iGPU (8700K - UHD630) in BIOS and also not using InjectIntel, but the results are still the same and I don't know how to check if iGPU is turned off.

Also is it OK that my dGPU is showing as Radeon Pro 570 instead of RX 570?

Thanks in advance.
