OK, I found it in my iPhone copy of the manual, which is hard to do. Check out setting a2 on page 282 or in your camera's custom settings. You can select to release whether in focus, or release only when focus is confirmed.
Edited to add: This is for single servo. I think focus confirmation in continuous mode is an excercize in futility, but that's my bias.
