How to get and set txpower for Thread Mesh Networks?

Does Mbed OS 5.15 provide an API to access the Tx power?

On a Silicon Labs MGM12P board, for the same conditions, i.e. distance, antenna, etc., I am observing a far lower signal strength by default when running Mbed OS 5.15 firmware (-46dBm) as compared to Silicon Labs firmware (-18dBm).

The chip has a maximum of 17dBm output. Silicon Labs firmware defaults to 17dBm but MbedOS firmware seems to be defaulting to 0dBm, hence the difference. Is there an API call to read/write the tx power setting?
