(OpenCore 0.6.1) Built-in screen blinks on Acer VX15 i7 7700HQ with HD 630

Hi! I'm new to Hackintosh and everything is perfect except for one thing. My laptop's main screen (built-in 15.6) is blinking from time to time in random apps and random moments. Alredy tried lots of common solutions but no success. I'm leaving all my configs, photos and videos to demonstrate.

My EFI repo: https://github.com/fbocolowski/VX5-591G-OpenCore
My BIOS settings: https://imgur.com/a/4fFRYr3
Video showing single screen blinking: https://www.youtube.com/watch?v=8RW2cK5r2Gg
Video showing that only the built-screen blinks (even mirroring): https://www.youtube.com/watch?v=xLNzTc0AamM

Alredy tweaked my DeviceProperties to lots of combinations and no results.
Tried switching macOS versions (Mojave, Catalina previous updated and Big Sur).
Tried tweaking WhateverGreen.
Tried using custom macOS versions such as Olarila.
Tried switching to Clover EFI and re-doing all configs.
None of that worked.

Anyone can help or give some advice?
