Motors making a very high pitched noise

Hello, I started using a pair of 6374 Bioboards motors but they make a very high pitched noise when they get turned on, from pushing the throttle a bit I can hear them even when they are not moving. I know that BLDCs make noise but after looking at some videos they don’t seem to have this irritating noise all the time, any parameters I can modify in the VESC to mitigate this? Thanks.
