Niresh, first of all, thank you for your help.
I can't disable the NVIDIA GPU, even on the BIOS settings, there is no such option. I have even looked on the manufacturer help fórum, there is nothing in that regard.
Is there a way to make these DSDT patches on your release? Could you make a guide or a video of it? I tried looking at some guides on tonymacx86.com, but it's too complicated for me (and also, I don't have a running version of MacOS on my computer).
