Screen Flickering

I posted this a while back and you guys were as confused as me. Some said display dying and others, outdated drivers.

The cause is still unknown but I've narrowed it down a bit. I have Asus TUF. It has a GPU Ultimate Mode. I think what it does is runs the laptop on dGPU and not on the Ryzen 7 6800h's Radeon Graphics.

So if I run ANY game on Ultimate Mode, this flickering never happens. But if I play on Standard setting, which also has dGPU on, 9/10 times it flickers. I read a post an year back which said it's caused by faulty AMD drivers and to turn off AMD freesync. I did it and it worked back then. Not for last 8 months tho.

All my driver's are up-to-date and I've reinstalled them countless times. I've factory reset my windows but this comes back.

You guys got any idea??
