I am not an expert, but first of all what server are you using X or Wayland.
I am not an expert in Wayland, but X is able to utilize any GPU in any
number.
If it does not this automatically you have to manually configure the server.
There are numerous guides on the internet.
It also depends how your MoBo is designed to work. Some do not allow using
both internal/external GPU.

Last but not least - why many GPUs but one monitor? It makes no sense. It
should use the one where the monitor is attached, but usually monitors have
more inputs, which you can utilize.
