Two reasons for this change:
- `intel` drivers are not updated from quite a long time (since ~2019),
and `modesetting` is the preferred one for Intel iGPUs.
- Technically you may want to disable NVIDIA GPUs on laptops with AMD
processors too.
We don't want to pin `modesetting` here because it is already the default
since PR: https://github.com/NixOS/nixpkgs/pull/111551.
This is already used in XPS 15-9560, but instead of defining it in XPS
15-9560 let's create a separate profile and expose it for those who want
to disable their NVIDIA GPU.
