I'm not aware of any updates for the Vector controllers that would actually reduce the motor noise.
The VEC controllers are Sine Wave controller and they greatly reduce the motor noise under load compared to the HPC square wave controllers.
I suspect that the noise you are hearing is the typical motor noise which occurs when you manually spin the motor (without using power from the controller), so it is unlikely that you will be able to reduce it.
It might be different if the noise was only evident while the motor was under load, but if the motor is still producing the noise while it slows down after quickly releasing the throttle, then the controller is unlikely to be causing it.
