Need help installing a new GPU

I recently picked up a GTX 1050 Ti and installed it into my PC. My motherboard is an ASUS Prime B450M-A, which features integrated graphics.
Now I am somewhat uncertain about how to configure the system so the new card operates with its optimal settings. I am not entirely sure if I have properly disabled the integrated graphics, as the system is currently claiming that the drivers for the GTX 1050 Ti are incompatible with the onboard graphics chip on the motherboard.

What would be the appropriate course of action here?
