How to set my laptop runs on Nvidia and my 2nd monitor (HDMI connected) runs on integrated graphics

Hi guys,

I have a 2nd monitor connected via HDMI to my XPS Dell Laptop. How can I set my laptop runs on Nvidia and my 2nd monitor (HDMI connected) runs on integrated graphics? Right now my 2nd monitor runs Nvidia card which is such a waste. I have checked some options in Nvidia Control Panel but can't find the solution.

Thanks guys.
