High Pitch Noise from Dash Area

This has been very bothersome to me. There is a high-frequency tone being emitted from the electronics behind the dash. It seems to come from the area behind the small HVAC display but I've noticed the noise even with the HVAC system OFF.

This is not a fan noise it's a ringing/resonance of an electronic component that results in a high frequency tone.

We test drove several G05s and I didn't notice it until we got in the one that picked us up from the airport for PCD (and of course our car).

This is my wife's car so I can't simply surrender it to the dealership at my will so I'd like to know if someone has had this resolved before I pursue.
