The Acquire and Release resource control setting in the application is not configurable for the Google Dialogflow recognition engine.

By default, Dialogflow uses the Acquire and Release as Needed option. The Dialogflow ASR resource is acquired when the first grammar is loaded (to send the Welcome event). The Dialogflow ASR resource is released when AAEP detects an error communicating with Google or when the response from Google contains the JSON intent object with the endInteraction key/value pair set to true.
