I hear very annoying and weird high pitch noise while the board is not under load (while printer is idle). Is there any way to suppress it?

Is it coming from the board, power supply or stepper motors?

Is coming from the board. I suspect that it is dc dc converter because when I add some load (connect pi to boards pi header) the noise is almost gone.
