Asus TUF A16 AMD Laptop wakes up immediately after sleep when External Monitor is plugged in

I'm using the ASUS TUF A16 which comes with AMD Radeon RX 7700S dedicated GPU, and an integrated Radeon 680M. It manages them through a MUX switcher in the laptop, with the only option to run dedicated-gpu only on boot menu. I'm on KDE-fedora, but I have replicated the problem on multiple distros and desktop environments. The problem I'm having is that the laptop goes to sleep and immediately wakes up when my external monitor is plugged in. I've done some research and troubleshooting, and I've come to think the cause is that the external GPU restarts whenever it goes to sleep with the external monitor on, possibly related to AMD's MUX switch, but that's just speculation. I assume this is because the hdmi is run by the dgpu, and doesn't work with the igpu, but how to fix it has proven so far to be out of my league.
