centos – How to disable the integrated graphics on Dell Precision 5530 (causing nvidia to not be default graphics for all)

Good morning,

I have a Dell Precision 5530 that I have installed CentOS7 on. Generic install without access to repos. From there I disabled nouveau and installed the nvidia drivers (NVIDIA-Linux.run). This was “successful”. After a reboot logging in works.

When attempting to open nvidia-settings, it fails fails to come up but nvidia-smi works (leading me to believe the nvidia drivers are loaded). Looking at lshw -class DISPLAY it shows that nvidia is used as the 3D renderer and the integrated graphics are set as the rest (below info). OpenGL is showing as using the integrated graphics which is an issue as well (see below for screen captures).

How do I disable the integrated graphics to force nvidia to be used for everything? Or at least force OpenGL to use the nvidia card instead of the integrated graphics? Thank you.

General info below
