Nvidia Optimus laptop always using Nvidia GPU and never the integrated one

I have successfully installed Nvidia proprietary drivers on Debian 12 but now my system is always using dedicated Nvidia GPU and never the integrated intel one to save battery life. I am pretty sure this is happening because of my xorg config which is here: `Section "Module" Load "modesetting" EndSection Section "Device" Identifier "Nvidia Card" Driver "nvidia" VendorName "NVIDIA Corporation" BusID "1:0:0" Option "AllowEmptyInitialConfiguration" EndSection Section "ServerFlags" Option "IgnoreABI" "1" EndSection ` If i don't use this xorg config Nvidia drivers can't find the Nvidia GPU and i get error (EE) No devices detected and (EE) no screens found(EE). I am using legacy drivers version 390 because my GPU does not support any newer drivers. Does somebody know what i need to change so the drivers can still find my GPU but make the intel iGPU default?
