only tested in Monterey, it removed nvidia drive natively due to known issue in Monterey. this EFI enables eGPU by default in OpenCore config.plist. You can follow post installation step to install nvidia drive if you intended to enable mxm graphic card.

dual-GPU(Nvidia/Quadro) support (post installation):

AppleALC for Dell Precision M4800 support(layout-id 59) has been merged to acidanthera/AppleALC from release version 1.7.1. You would be able to update the driver from acidanthera/AppleALC going forward.

ssdt was customzied based upon my hardware list. Probably you need to recompile based upon your own hardware configurations. if you have already cloned this repo in macOS, just simply modify SSDT-Dell-M4800.dsl in any text editor, and then save and run make all in terminal. or you can also compile it in Linux or Windows platform if you have correct iASL version.

Wireless Driver:

this EFI is based upon Broadcom BCM4352. For Intel WIFI adapter, you may remove below 4 kexts from my EFI package instead of appropriate Intel driver AirportBrcmFixup.kext BlueToolFixup.kext BrcmFirmwareData.kext BrcmPatchRAM3.kext In the meanwhile, you can remove line 1392-1421 in dsl file SSDT-Dell-M4800.dsl, and then recompile to replace SSDT-Dell-M4800.aml (It's not mandatory)
