Radeon RX570 black screen after wake - RadDeInit doesn't work?

[cowcowpod]

Hi, I recently got an MSI Armor Rx570, and it works mostly OOB.
I know it's a non-reference design, so the ports are different that what MacOS expects, but I have WEG for that.
It successfully goes to sleep, but on wake there is no Video output, and the same with other ports. It usually reboots after a short period (5 seconds to a minute).

The IGPU is in headless mode. Using an id with connectors yields the same results.

In BIOS, i have selected the dGPU as primary, and disabled multi-display. I have also disabled S4/S5 deep sleep, USB wake support, as well as Wake on LAN.

HALF-SOLVED: Enabled BIOS options Legacy Option ROMS, set IGPU as primary. Now, it's a "blind-boot", but at least it wakes!
However, isn't this supposed to be fixed by WhateverGreen, or RadeonDeInit?

I have the same issue with the exact same video card after switching out an Nvidia card (GT 710). Did you ever fully solve this and what's a "blind-boot"?
