The Duet 2 WiFi does not support stealthchop because it uses TMC2660 drivers which don't provide said feature. That being said, there are tuning methods to reduce the sound level: https://duet3d.dozuki.com/Wiki/Reducing_Stand-Still_Noise
Not sure if these apply when running (rather than at standstill) but it might be worth a shot.
