Based on how difficult it was for the authors of this piece to even get a web browser to work or to find drivers for hardware, I doubt you'd get DX10+ to work.

If you can get Vulkan to work, you can potentially use DXVK and VKD3D for DirectX 10-12 support.

IIRC GTX 700 was the last nVidia generation to have XP driver support so you probably wouldn't be able to get it working properly anyway.

You might be able to copy dxvk and dx11/dx12 libraries from Proton/Wine. Not sure if it'll work as you'll somehow need to find a way to get vulkan to work, but sounds like a good weekend project to me.
