Copying between GPUs is a thing, that's how integrated/discrete GPU switching works. So if the drivers provide full vulkan support then rendering on the nvidia and copying to another GPU with outputs could work. And it's an ARM CPU, so to run most games you need emulation (Wine+FEX), but Valve has been polishing that for their steamframe... so maybe?

People have gotten games to run on a DGX Spark, which is somewhat similar (GB10 instead of GH200)
