no setting menu (icon) on instrument cluster

No
All settings are done through the infotainment screen if you have the Ultimate version.
Sound alerts are set in the map and navigation screens.

Surprised dealer did not go over those settings with you, it's a major function of the car. My salesman had to have me sign a statement that he went over settings.

as other users have suggested, other than muting alerts on the map app, there is no way to turn of the red light camera and speed warning via the setup in the infotainment screen but according to the hybrid/phev user manual you have the option to turn it off via the user setup/convenience screen, no such setting found on my vehicle. if you need nav guidance, you need to remove muting on the map app....pretty convoluted if you ask me...any other way to mute alerts that you know of ?
