First the Auto-Detect is temporarily disabled until further notice.
Here is the latest AMD VGA Driver for your 7950X APU: https://www.amd.com/en/support/apu/amd-ryzen-processors/amd-ryzen-9-desktop-processors/amd-ryzen-9-7...
Since you have a Nvidia GPU card installed BIOS automatically made that the Main Display adapter and the 7950x is secondary.
There might be a AMD/Nvidia VGA Driver conflict.
Use DDU with the internet disconnected and deleting, if created, both AMD & Nvidia Driver Installation folders at C:\AMD & C:\Nvidia BEFORE installing the VGA Drivers.
Install the latest AMD APU Driver and see if it installs correctly and in Device Manager there are no errors with either the AMD nor the Nvidia GPU card's drivers.
Then upload a image of GPU-Z which will show if the AMD has enabled all the correct API's for your APU IGPU.
