Force Wayland with Gnome after ignoring nVidia GPU in favour of AMD iGPU

I have a laptop with an nVidia GTX 1650 and an AMD Ryzen 5600H which has an onboard Vega iGPU. I only use the Ryzen for graphics, and the nVidia GPU is only present for accelerating video encodes and the occasional TensorFlow experiment.

How do I force Manjaro Gnome to boot with Wayland support, using only the iGPU for rendering the display and ignoring the nVidia GPU?
