IWR6843AOPEVM: How to remove capacitor whistle

Part Number: IWR6843AOPEVM

Hi expert,

Currently customer manufactured their products followed IWR6843AOPEVM design but found there is capacitor whistle on some of boards. We also tried on two EVMs, one is slight and the other is serious. 

The image we used is \mmwave_industrial_toolbox_4_9_0\labs\people_counting\overhead_3d_people_counting.

Question is if you have any suggestion to reduce this noise.

Thank you

Allen
