Turning Bluetooth Off

Is it possible to turn off bluetooth, specifically on the boron? I would like to minimize power but also minimize electrical noise.

What device OS version are you running?
AFAICT prior 1.2.0 BT/BLE is only one in Listening/Setup Mode and with 1.2.0 you should be able to switch BT/BLE on/off just the same as all the other radios.

I’m currently using 1.1.0. I didn’t see an API for BT other than the “Mesh” category. Is there a new API in 1.2 that I’m not seeing?

Yes, there are new, not yet documented features currently undergoing some testing by the G3CC participants.
