it's a layer for laptops to change which device to use by default depending on whether it gets it's power from the mains or its battery

- The ICD determines that the hardware really doesn't support Vulkan
- There's a bug in the ICD
You're best bet is to work with Nvidia at this point. Pass along the VIA.html to whatever bug you file to help reduce the initial back and forth.
That Optimus thing in your log is really making me paranoid.
Try this guide (if any of it is applicable): https://devtalk.nvidia.com/default/t...d-laptop-gpus/
I.e. try to set "Preferred graphics processor" to "high performance" in the NVIDIA profile for vulkaninfo, if there is such option there for you.
Based on the log you only have the SDK RT. Try to uninstall: driver, SDK, Renderdoc, any and all Vulkan RTs. Then install only the NVIDIA driver for now and test vulkaninfo. I think it should install 1.0.37 Vulkan RT as part of it.
