Default Engine reving like engine braking when deaccelerating

2024 350h. I noticed around 30-40mph, let go the accelerator, the engine noise goes up like engine braking. It's not electric motor noise. Is this normal?
Shifter in Drive , level ground.

Read this......(Courtesy of WellsB)

It's not overcharging. It is preventing overcharging, and also preventing excess discharge. It's a relatively small battery in a relatively heavy vehicle. That means it will both discharge and charge fairly quickly. I imagine that driving style would play a part in it as well. Of course, something might actually be wrong with some vehicles, but unless we know what the vehicle is supposed to do under different conditions, it's a guess as to whether it's normal or not. I do wish there was a guide on what to expect in the manual.

I did find mention, in the manual, of predictive functions that could be causing perceived issues.
