Hello,
I have a Yoga Pro 9i with an Nvidia 4060 dGPU. When I run Gnome with Wayland, it seems that Gnome-Shell engages the dGPU to render the desktop:

This seems like overkill and I would like for Gnome to use the Intel Arc iGPU, leaving the Nvidia powered off.
Any idea how Gnome decides which GPU to utilize?
