Lenovo Legion 5i 15IMH05H EFI Issues

[Zoom]

Hello, I have Lenovo Legion 5i

Specs :

CPU: Intel I7 10750H
RAM: 2x8 GB DDR4
iGPU: Intel UHD 630
dGPU: Nvidia RTX 2060

I followed the opencore guide and managed to install macOS Big Sur, but some stuff are not fully working such as

• Trackpad
• Disabling Nvidia GPU
• Power Management (Battery drains very fast)
• Changing Screen Brightness doesn't work (from the preferences nor by FN Keys although the FN keys show brightness changing)

For the nvidia dGPU I have used the ssdt provided on the opencore guide and changed the ACPI path but when I try and boot into macOS the fans ramps up the fan to the max and in a span of 10 seconds the laptop shuts down

Then I tried another ssdt for disable the dGPU it changes the ACPI path from \_SB.PCI0.PEG0.PEGP to \_SB.PCI0.PEG1.PEGP and I don't know if that works or not, I can boot normally into macOS with it but the battery drain still exists.

for the trackpad, when I go to the trackpad window in preferences I see the options and that it sees a trackpad, but i can't move or click with the trackpad as it doesn't work.

I have downloaded the EFI for notebooks (CoffeeLake Plus and CometLake) in there and tried to boot with it, first i got this error

So I added NVMeFix.Kext and booted again and I got this error
