     * When set to {@code false}, we will not connect A2DP and HFP on a dual mode (BR/EDR + BLE)

     * device. We will only attempt to use BLE Audio in this scenario.

     * When set to {@code true}, we will connect all the supported audio profiles

     * (A2DP, HFP, and LE Audio) at the same time. In this state, we will respect calls to

     * profile-specific APIs (e.g. if a SCO API is invoked, we will route audio over HFP). If no
