My current configuration:

2019 MacBook Air (MacBookAir8,2, 1,6 GHz, 8 GB)
macOS 10.15.7 & Win10 20H2

eGPU RX 570 -> R43SG-TB3 -> Port 1
eBootcamp HDD -> USB 3.0 adapter -> PD HUB -> Port 2

Power Chord -> PD HUB
eBootcamp HDD -> USB 3.0 adapter -> PD HUB
4x USB 3.0 HUB -> PD HUB

Keyboard -> 4x USB 3.0 HUB
Mouse -> 4x USB 3.0 HUB

On the Mac side everything is fine, with Bootcamp it's a different story.

I have to reboot the computer until the video card is correctly recognized and I can only tell this after the system boots up, when the video card fans stop spinning.

I currently only use EFI fix + Error 12 regfix, everything else is identical to a normal Windows system, including system updates and drivers.

When the card is recognised it runs fine on Windows, but I have to make numerous attempts. Is there a more reliable way to boot?
