Can Engine Driver use DCC-EX TrackManager?

Yes, when using the DCC-EX Native protocol. The DCC-EX Engine Driver documentation lists TrackManager control as a Native protocol feature, including the ability to change track/channel type and state.

This is more advanced and should be used only when you understand how your CSB1 outputs are configured.
