Yes, this works for many laptops but it depends on how the laptop is internally wired. We have many members that use their iGPU for Linux, and the dGPU for the VM.
I haven't tried in about 6 months but I had issues with reusing that same dGPU if I wanted to use it for Linux gaming when the VM is offline. I thought it would be easy to bind and unbind it as needed but had issues with doing so. Is this a possible/recommended setup, is there another alternative or I shouldn't bother trying?
