tldr: just don't use Bootcamp

If everything else you tried failed at getting eGPU to work on Bootcamp'ed Windows, try this out, why not.

Cons of this method: you will not be able to use mac hardware in windows - keyboard lights, F function keys, delete key (it's just backspace), speaker, microphone, and camera.

 

How to install windows on a partition of your Mac without using bootcamp:

1: Download windows iso (from TechBench by WZT, windows 10 1903 18362.30 version is the best? idk).

2: Open the iso and copy all files to somewhere - a USB, or a small partition on your mac.

3: In MacOS, go to disk utilities, select the main drive and create a partition under type MS-DOS with as much volume you want your windows to have.

4: Reboot while holding option + R, with the iso file USB plugged in. Select boot windows from EFI (or just windows if you used a small partition on your mac).

5: Follow windows install process. When you are asked to select where to install windows, select the partition disk from step 3 and click format, then continue to install on that disk.

 

What to do after manually installing windows:

1: windows will not recognize your iGPU. Connect to internet and either wait, or go in device manager and search for updates, or manually find your driver on the internet.

2: plug in your eGPU, same step as 1.

 

Now you are all good. At least I'm all good - on mid-2015 Mac, Razer Core X, GTX980. None of the problems in The Bootcamp eGPU guide will be encountered.

 

Ways to deal with the cons: use external headphone and ahk to deal with sound and keyboard. Or install a separate bootcamp windows, or learn to use the mac os.

 

Edit: if I try to install bootcamp assistant through usb, it will work with egpu until restart. Then after restart windows proceeds into detected a problem - restart - trying to load recovery - restart loop until egpu is unplugged. 

The mac hardware recognitions immediately work after installing bootcamp assistant, it is something that needed restart that mess up egpu. So if someone knows bootcamp assistant better, please check this.

I have been considering this route. Have you tried to install the Bootcamp support software after setting up your windows install outside of bootcamp? I wonder if that would get everything else working without breaking the smooth eGPU set up?

If you meant by downloading windows support folder from bootcamp assistant in mac os into a usb and then run it in windows, yes I have. 

Immediately after installing, everything seems to work, egpu and hardwares, but I haven't tested for extended periods of time. But if I restart I go back to windows problem restart loop if egpu is plugged in.

So if you want to restore and install bootcamp on every start... maybe.

I've also tried deleting stuff in the bootcamp assistant folder leaving only mac hardware things, thinking it might be the graphics drivers in it messing things up, didn't help. 

Seems to me there is something built inside bootcamp assistant that's intentionally not allowing egpu.

There maybe a way to tweak bootcamp assistant more, or another third party program that makes windows recognise mac hardware. But I just settled with it for now.
