FYI: The method is named DOFF not _DOFF (_DOFF can't be used as it is 5 characters... ACPI names are limited to 4).

Thanks for letting me know. There are probably many problems I need with your help :p

As per guide, DropOem must be set true with patched SSDTs in ACPI/patched.
You have it set false.
I didn't check anything else, due to this obvious mistake.

Hi Rehabman you are a genius. Thank you! I am able to boot into macOS now! I didn't dropOem as one of your guide (power management) mentioned not to drop except for older laptops hence I didn't drop. Is it possible to help me check that the Nvidia is fully disabled? Attached is IOReg, Clover, Kext Output and Download/Rehabman for your perusal. Thanks!!

Bad idea to use ACPI files from another computer.
Patch your own.
