ZenBook Display Flickering Issue - Need Help Troubleshooting

[RubyGrace]

I've noticed that the screen on my ZenBook has started to flicker intermittently. It's not a constant flicker, but it happens often enough to be bothersome. I've tried adjusting the brightness, updating graphics drivers, and even rebooting the laptop, but the issue still persists.

May I know which model of laptop you are using? 
How to find Model Name
If the flickering occurs even within the BIOS, does the screen continue to flicker? 
If the flickering persists within the BIOS, it could indicate an issue with the screen itself, and I would recommend sending it for repair and diagnosis.
