With the acoustic uBass I'm fairly certain the pickup sensor (piezo) is mounted under the bridge on the inside. This is designed to sense all vibrations on the top and later to amplify them. You might be able to use a filter inline to reduce the noise created in the range of moving your hand around? A person could have a similar problem with a coat sleeve when playing a double bass with a piezo mounted on the bridge.
For what it's worth, there's a few seconds showing my right hand style at 0:58 in the video below.

And, as if it matters, I was not playing the bass on the song recorded in the video but those are my fingers in the video. This was the first time I played a bass for more than a few minutes, bought one two days later.
