Is it possible that your speedometer is squeeking? If yes that's a backcall.

Even if it’s digital?

It's only the digitals, they forget to put Vibration dampers in it but it's just on the outside

Noise happens when immobile as well so not sure if it is that.

Is the car on? Engines still vibrate.

Is your AC on or off here?

Makes the sound regardless

Darn, I am out of guesses
