Help with IGPU

Hi r/hackintosh

I am having a small issue

My Specs :

I3-6100 , 8gb ram , GTX970 , SSD

My issue :

I have installed Big Sur using Opencore while display is connected to the GTX970, Due to no support for the GTX card i am wanting to use the inbuilt IGPU. Switching to IGPU causes Kernal panics

​

What i have tried :

Booting as usual but connecting HDMI to Onboard Graphics instead of GTX card - Fails to boot reach Apple logo and then the screen turns "Teal" and Pc reboots

​

Editing Config.plist to have Boot arg of "wegnoegpu" - Does not boot, Do not reach Apple loading screen simply pc Kernal panic before this stage.

​

Please let me know if anyone has any ideas!

​

Looking for either a way to use the IGPU (intel graphics 4000) or to force the gtx 970 to display full Resolution (1080p This seems impossible due to no support )
