I never figured out how to toggle graphics between intel integrated and nvidia gpu as I also want to use nvidia gpu fully for CUDA algorithms, is there an app or something to do that?
I don't know if this is what you're looking for, but I use the system76-power extension (https://github.com/pop-os/system76-power) to toggle between the integrated Intel Xe unit and the dedicated Nvidia GeForce GTX 1650 in my Galago Pro. While at first glance it might seem that it's a System76 utility for a System76 distribution on System76 hardware, I'm currently using it on Fedora, and the hardware itself should be pretty standard despite the System76 branding. Using the glxgears graphics demo, I can invoke 'glxgears -info' to use the Intel GPU, or '__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears -info' to force use of the dGPU. You don't get the fancy-shmancy menu that you do under Pop!_OS, but it has a perfectly workable CLI.
