G-Sync Compatible not working when multi GPU connected

KDE Plamas 5.26.3
Kernel 6.0.8-1
Nvidia Driver 520.56

My setup:

1 Monitor Gsync Compatible
1 3070 Ti - For Gaming - Connected to the monitor
2 3060 Ti - For Mining

If I connect only 1 GPU, G-Sync works perfectly without any configuration.
If I connect more than 1 GPU, G-Sync just does not work and the setting does not shows up on NVIDIA X Server Settings.

Is there a way to fix this?

Anyone?
