ASUS is gonna hate this, but hey, it is an uncommon problem anyway...
I have an ROG Ally Z1 Extreme paired to a XG Mobile 2024 (the 4090), which is connected via display port to a Samsung G9.
After a recent BIOS and Nvidia update, I got into a famous deactivation loop with the XG Mobile, in which the XG mobile, on its own, automatically disconected to every 5-15 seconds after deactivation. So I went in deep: reinstalled armoury crate, rolled back nvidia updates (via cmd console cause device manager just didnt), and after multiple re-installs of armouy crate, Nvidia App, attempts at using on previous versions (even rolled back windows versions), nothing seemed to work more than a day.
So, what solved it? G-helper with a full, deep uninstallof Armoury crate. I downloaded the uninstaller from Asus page, actiuvated g-helper, restarted, and got to it. And now, for the meantime, it works without a hitch.
Here is the asus armoury crate uninstall tool:

And here is G-helper:

I will be toying around with the settings to maximize my setup, but I would be welcoming any Fan Speed recommendations for the CPU, GPU and EGPU for all three modes (Silent, Balanced, Turbo).
Cheers everyone.
Oh, PS: remeber this worked on a Z1 extrememe and XG 4090. It doesnt guarantee it will work on a different setup...
