Disable dGPU on dell precision 7740

I have a dell precision 7740 with Core i9 9gen CPU and Nvidia rtx3000 GPU. The problem is in its BIOS when I disable switchable graphics, it disable the intel UHD 630 not the Nvidia card. So my question is is there a solution for this issue? does kexts like whatevergreen have the ability to somehow use iGpu instead of dGPU despite this config? Or maybe enable switchable graphics and config opencore in a way to do this? Because right now I have a Sonoma that has 7mb graphics without acceleration and it is very slow on graphical effects of the os.
