The fabled Code 43 issue

Issues & Assistance Newbies
1

Hello.
I have been struggling with setting up GPU passthrough with QEMU/KVM for the past few days now, with no end in sight. Everything works, except the GPU passthrough, I get the classic Code 43 code there, being stuck in 800x600.
For context, I have followed SOG's "tutorial" on how to do his scripts and passthroughs, with additional help from the Arch wiki.

It seems to me that whatever I do, I'm not able to get my GPU to passthrough without getting code 43 on Windows 10, hopefully someone more versed can help me with this.
I use a R5 1600 and Zotac 1070ti mini.

I have attempted the following:
This KVM yoke in the VM XML conf.

<hyperv mode="custom">
      ...
      <vendor_id state="on" value="garfield cat"/>
    </hyperv>
    <kvm>
      <hidden state="on"/>
    </kvm>

Gpu reservation errors, and after trying the commands, I get the following.

vfio-pci 0000:09:00.0: BAR 3: cannot reserve [mem 0xf0000000-0xf1ffffff 64bit pref]
...
echo 1 > /sys/bus/pci/devices/0000\:00\:03.1/remove
echo 1 > /sys/bus/pci/rescan
...
""/""

Most interestingly, the pre-dumped vBIOS for my GPU was about 4 times as big my own vBIOS dumped from my GPU, not to mention that the beginnings of their roms were different.
For some reason, my graphic card's vBIOS did not want to display anything on the screen, and the pre-dumped worked just fine.
My 1070ti's rom:

U.s.K7400.L.w.VIDEO

Pre-dumped 1070ti's rom:

U.y.K7400.L.w.VIDEO

Any help is greatly appreciated, I am at a loss for knowledge and ideas.

Did you install in legacy boot mode on purpose?

Edit: Disregard, now that I look into it I think it should be fine with or without EFI.

Some BIOS menus have a VT-d/IOMMU option you have to turn on, did you already check?

Edit 2: You are also several BIOS updates behind. This could be a factor. ASRock > AB350M Pro4

All virtualization and iommu options are enabled.
I will attempt the BIOS Flash now.

Updated BIOS, ver 2.3 > 3.4 > 5.1
Booted into VM after adjusting options to the new ids
I still get error 43
