How to enable OTA DFU on DWM3001CDK

Hello there,
We’ve successfully purchased a set of DWM3001CDK but we’d love to enable the OTA DFU on the board.
Following the tutorial at, still, we are not able to enable the DFU OTA on the DWM3001CDK board.
We’d love to know what is the process specifically for DWM3001CDK to enable OTA DFU, and should there be any example on this?
Thanks and much appreciated!
