LOWER the LoRa TX Power of the T1000 Tracker

Hi all!
I live in the AS923-1 LoRaWAN Region. The MAX legal transmit power here is 20mA.
However, I want to use the seeed tracker in a low radio signal location.

The location’s policy is no device may transmit over 10mA of TX power.

SO! My question is, can I LOWER the TX power of the LoRa module on the T1000-a Seed Tracker?

Thank you very much!
