Force a VKD3D game to run on an NVIDIA dGPU using NVIDIA Prime Offloading

If I'm using VKD3D how can i force a game (specifically Empyrion) to run on my dGPU?
for openGL games i would add

prime-run

prime-run

before the launch command, and DXVK does it automatically without needing that. Unfortunately VKD3D doesn't.
Any help would be appreciated, thanks!
