Description

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Should detect my RTX 4060 TI as only GPU.

### Actual Behavior

I'll be happy to have multiple NVIDIA GPUs but I only have one
