Alienware m16 r1 (AMD) weird screen flicker in dgpu only mode!

I just bought an Alienware M16 R1 (AMD) with an RTX 4080 and a Ryzen 9 7845HX. I want to use the MUX switch on this laptop, but after enabling it, the screen starts to flicker randomly for a second every 3 to 5 minutes. I’ve tried the latest BIOS, reinstalled drivers, and even reinstalled Windows multiple times, but the issue is still there. There are many people on Reddit experiencing the same problem. Is there any solution for this issue?
