Using GPU ports with iGPU graphics

Is it possible to run MacOS on the iGPU while still using the ports of my RTX2080?

I'm not doing any graphical intensive work on MacOS, but stil like to play games on Windows.

Specs:

CPU: i7-9700k

Mobo: AsRock Phantom Gaming ITX (TB3)

GPU: Gigabyte RTX 2080 Windforce
