Hello @clwood. You may be able to change it post-process through editing applications but there is no setting on the camera that will allow such a change. The change in aspect ratio from 4:3 to 16:9 (or 16:9 to 4:3) can only be done for recordings. There is more information here regarding photo dimensions for the HERO7 camera.
