I have multiple linux computers, from servers to a surface tablet, i am able to use all different generations of all nvidia, both permanently installed, and eGPU. It is not without any issue, but it works and is usable.

For me issues stem from x11 vs wayland (work computer is ubuntu due to company policy), or egpu shenanigans which I feel is platform agnostic

This is possible, and exact directions will vary on distribution of the vm client. I personally do this but with split horizon dns and dnsmasq on a vm.

impossible to leak is where it gets tricky, and that will require an understanding of networking in your distribution. there will also be tutorials on this, but it’s very easy to mess up.

hardwire for testing? then when settled do the full install. maybe use a different laptop.
