There are inappropriate changes to DSDT.aml (like you're using a buggy iasl for disassembly).
No need for patched DSDT for brightness control.
Remove ACPI/patched/DSDT.aml.

I remove the DSDT, why OS didn't start? Should i disable discrete card?

See guide (can be easy way, but does not actually disable the device):
https://www.tonymacx86.com/threads/...-only-ran-for-0-seconds-with-dual-gpu.233092/

Or (better... actually disables the device):
https://www.tonymacx86.com/threads/guide-disabling-discrete-graphics-in-dual-gpu-laptops.163772/

Or disable it from BIOS (if BIOS option available).

I follow the second Guide and now the OS boot and brightness works but it don't return from Stop (Black Screen) or better it return from stop but the Display remaining black.
