Should you ever desire feedback for focus lock, it is possible to turn on only an audio confirmation. If I remember, it is a simple beep and you can select between three loudness levels.
I used audio confirmation with the back button method in order to help me understand how to optimize AF menu parameters for different types of scenes and focus objects.
