The “connmanctl disable wifi” comman disables the WiFi technology on the system level, effectively turning off WiFi connectivity through ConnMan. This means the WiFi will no longer scan for networks or connect to them until it is re-enabled. The WiFi hardware module networking capabilities are deactivated by the operating system.
For the Bluetooth use “connmanctl disable bluetooth”

@alex.tx
So, is this a permanent disable, or must be run every launch?

Thanks!

By default WIFI and BT are disabled.

@alex.tx ,
Is there a way to verify this?

Thanks,
Steve

You can verify it by running connmanctl technologies command

@alex.tx
ssh logging in under torizon and even doing sudo connmanctl technologies, yields connmanctl: command not found

running torizoncore 6.4.0

To disable WiFi, you can use the command nmcli radio wifi off , and to check the WiFi status, use nmcli radio wifi . If you do not require WiFi and Bluetooth (BT) functionality, consider using the Verdin i.MX8MP module, which comes without the WiFi/BT module assembled
