Currently on wayland with an nvidia dGPU

I generally would like to leave the gpu mode to hybrid mode to save power and occasionally run a program using the dGPU specifically. This program requires openGL support.

Is there a command I can type to start a program using the dGPU?

Apparently in windows, you can right click on desktop shortcut and "run with high performance GPU".

Wondering if this is also possible with wayland-nvidia.

I found this working in Fedora. When running the program:

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia <app_name>

Source. See the "Finer-Grained Control of GLX + OpenGL" section.
