@raul_fernandez, I've got Big Sur 11.01 and Windows 20H2 (OS build 19042.685). I didn’t do anything other than what I wrote, so no - no modified EFI boot loader or whatever.

 

2018 MBP 15" 2.9 GHz/1TB/32GB + Sonnet Breakaway 650 + ASUS ROG STRIX Radeon RX Vega64 8GB OC Edition + LG 34" Ultrawide via display port

It has made it impossible for me with versions 20h2 and version 2004. When I install these versions I get hung right at the start of Windows (windows flags). The error it says is booteable error

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Just in case anyone was still following - I upgraded Big Sur to 11.1 tonight and bootcamp 1903v1 still works the same way - hotplug startup method.

I haven't seen any change in my set up either.

Latest Windows, Latest macOS, booting just fine via EFI Bootloader. 

Having issues with HDMI output but I have a feeling its my GPU/TV.

I had some time last night and tried the trick with the hedless adapter in addition to my external monitor.  On macOS Catalina Geekbench scores are double both OpenGL and metal. Would that translate to better gaming performance. 

On bootcamp I did not manage to make it work as the display menu window shows on the headless monitor and by the time I try to grab it it defaults back to mirroring.

I upgraded to Big Sur 11.2 today and my 1903v1 setup still works like before... yay.  I was afraid some firmware changes were gonna break it.
