I had been trying to get my Windows 10 VM for 3 days already and I've just about had it - I figured this warrants some help because I've just about exhausted the last of my brain cells! The gist is that I want to passthrough my card to the Windows guest but nothing I do removes this error.

VM Config
What I've tried
I have obviously followed the guides on PCIe passthrough from the Proxmox wiki and numerous other guides such as this with no dice. Tried several combinations of pcie on/off with rombar on/off. Moreover, I dumped my vBIOS with GPUz then gave using the romfile a shot. Needless to say that did not work either. I've also tried using this Nvidia KVM patcher some suggested which while it did solve the error 43 message, brought up a code 52 error instead. Whether I compiled it wrong or not, I'm not sure. But I'd rather not go that route if necessary.
In all the modifications, I booted into safe mode and DDU'd the graphics driver every time so existing driver conflicts is very unlikely. I'd also like to add that Windows does not detect that it is a VM based off of task manager as far as I know.
Also, I've added these boot parameters
All the methods I've tried to remedy this issue still ended up with a code 43 and it's driving me nuts! I'd appreciate it if anyone can offer some advice on what else I could do. I was hoping I wouldn't have to make a thread as it'd make me feel inadequate for not searching the forums hard enough but I seriously have no idea how to continue from here. If there's anything else I can provide I'd be glad to. Thanks in advance to everybody!

Also, I've added these boot parameters
quiet intel_iommu=on video=vesafb:off video=efifb:off inside /etc/default/grub because I had a hunch it had something to do with the host nabbing my card at boot - obviously as no LGA2011 CPUs have internal graphics. Alas, I come to the same conclusion.All the methods I've tried to remedy this issue still ended up with a code 43 and it's driving me nuts!
