RGB doesn't stop working

I’m using an HTCC-AB01 to send some data, when it goes on deepSleep the big led in the center of the microcontroller will turn on with white colors, I don’t know how to deactivate it. In the configuration before upload the sketch I have LORAWAN_RGB : DEACTIVATE, and I did not mention in the sketch the RGB, someone can help me?

The corresponding pin of RGB is GPIO4, please confirm whether GPIO4 is used in your code.
