This is exactly what "Optimus" and "hybrid graphics" is, the issue is that you need to configure that - laptops will provide information to OS "hey, this card has no video output" or "hey, there's an output MUX connected to output X on iGPU and output Y on dGPU", and drivers pick that up and know they have to setup transferring frames between the two or trigger the mux etc.

nVidia has also used the datacenter cards to run GeForce Now, at least for some lines of the cards, plus some of them come with license (or you can buy it extra?) for nVidia GRID that provides more flexibility for multi-instancing etc to run in virtual desktop
