Just to confirm my understanding, but unless my motherboard manufactured releases a BIOS update that contains the ABBA fix, Ryzen 3000 on X470 WITH passthrough, will not work?

Yes.....Or you can try this kernel.

I have tried it and just get blank screen when passing through.

 

I have tried passing through an RX 480 and a Nvidia Quadro 290. By try, I create a new Linux VM (ubuntu), use all the defaults. Then I tried passing through specific GPU BIOS files as well. Are there any other specific customisation or things to try? 

I had a bit of hell passing my rx 560 thru. I had to stub it from the system or i got nothing but black screens from it. Also im running legacy mode if it helps.

Can you point me in the direction of how to stub something from the system?

Good video to get you started

Hey another thing try legacy boot mode for unRAID. UEFI just did not work for me when passing thru a GPU.

And I can say that all of this successfully works. I have full GPU pass through working on this hardware:

MSI x470 Carbon running the Sep9 2019 bios update, booting in Legacy+UEFI

The patched kernel seen above.

Ryzen 3900x

Saphire rx 480 and a VBIOS file from tech powerup ending(Sapphire.RX480.8192.160921.rom), and has to be in a secondary slot, not the primary.

 

Never used unraid before so still working on figuring out how to architect this and get it working for my needs.
