Current High Sierra clover/ nvidia user who want to replace GPU to AMD RX6600, what need to be done?

Hi Everyone,

As title said, I have been using High Sierra for last 5 years because of the limited driver support for old nvidia GPU (750 series)

I am going to buy an used 1070 or AMD RX 5600/6600 and prone to the later RX models for their OS upgradability (but that's not for now)

Right now I just want to know "what need to be done" to the kext, cloverconfigurator before I physically put RX on the mobo?

I'm using clover and i5 gen 7.

Hope I can get some good advice from experienced.
