Remark: The solution is really very simple. Just follow those step:

0) Replace Apple AMD Drivers with BootcampDrivers.
1) Boot without eGPU
2) HotPlugeGPU => AMD eGPU will be yellow banged with error 12.
3) Uninstall it directly from Device Manager:

UninstallDeviceError12
UninstgallDeviceError12B

4) Reboot. Done:

UninstgallDeviceError12C

If will update my Bootcamp Guide with this plan. (@itsage, I can't edit my opening post there...)

It may be easier to put that into a script/tool. I use devcon and have had great success with it. Of course, it may be six in one hand, half dozen in another. I just prefer not to have to perform all of those clicks.

Hi @chris_moran. Your work is amazing, unfortunately it doesnt fully work for me. When i run the script with my needs (changing the Vega56 adress), it will always only remove my dGPU RP560X. Am i doing anything wrong? 

I've commented out the devcon remove dGPU to test if it would remove the eGPU, but havent got any luck with it...

EDIT:
Got the script working by changing the values for the eGPU manually. Now running into another problem:
The script can succesfully remove my Vega56, but reinitializes before my macbook is able to start the "power off" sequence. So, i removed the Sleep 5 (second to last line), but this didnt fix it. The Macbook still reinitializes my V56 card before it shutdown completely....

Nevermind, i see you unplug it directly afterwards the external monitors go black... I hoped to find a solution to keep the cable in
