2021 Ram 1500 HEMI eTorque engine whine at top of RPM range/shifting when accelerating hard. Almost sounds like a supercharger.

For a few months now my truck will make an extremely loud whine sound. It only makes the noise when I'm full throttle and the engine is shifting at the top of the RPM range. The noise almost sounds like a supercharger. I've seen a few threads that advised it could possibly be the eTorque generator, but it operates normally and battery voltage is good according to the dash. No CEL or other lights.
