There exist no good concepts yet to properly do this on Wayland unless you have an actual way to "physically" change the GPU via a relevant setting in your UEFI. The latter used to be around for old implementations of Optimus, so it is unlikely this will currently properly work.

Re: kde wayland session use intel instead nvidia

From looking at the source, the parts that have any chance of allowing this in any form are specific to ASUS laptops. What actual system is this? What's your lspci output? Do you have a option in your UEFI to explicitly switch the GPU mode to dedicated? If "works on Xorg" amounts to having created a xorg.conf and the relevant xrandr invocation to bend the logical outputs in a way that makes the intel GPU work as a dumb pipe for the image of the nvidia GPU then this is not generally going to work on wayland. Have you tested whether you can prime-run things?
