Need to disable integrated GPU when using A770

[rajpatel9498]

Describe the bug

My machine has i7-13700K CPU with iGPU as Intel UHD Graphics 770 and dGPU as Intel Arc 770 (8 GB). When trying to run following command to check whether the XPU environment is correct or not, running into an error which says PI_ERROR_INVALID_DEVICE.

python -c "import torch; import intel_extension_for_pytorch as ipex; print(torch.__version__); print(ipex.__version__); [print(f'[{i}]: {torch.xpu.get_device_properties(i)}') for i in range(torch.xpu.device_count())];"

To Reproduce

Steps to reproduce the behavior:

1. Machine with iGPU enabled + Arc 770 (8 GB)

Expected behavior

XPU environment should be detected correct

Screenshots

The error log is as following:
C:\Users\Raj Patel\.conda\envs\aipc_xpu\lib\site-packages\torchvision\io\image.py:13: UserWarning: Failed to load image Python extension: 'Could not find module 'C:\Users\Raj Patel\.conda\envs\aipc_xpu\Lib\site-packages\torchvision\image.pyd' (or one of its dependencies). Try using the full path with constructor syntax.'If you don't plan on using image functionality from torchvision.io, you can ignore this warning. Otherwise, there might be something wrong with your environment.

Environment (please complete the following information):

• OS: Windows11 24H2
• dGPU: [Intel Arc A770 8GB]
• iGPU: [UHD Graphics 770]
• CPU: [i7-13700K]
• Version: Tip of the dev branch 2486734

Additional context

I was able to fix this issue by disabling iGPU device from Windows Device manager.
