Do you mean interval? The answer is no, both the Pro and Zoom models have a set number of intervals, 2 seconds being the shortest. See the specification section of your manual.
Land based cameras allow 1 seconds (and sometimes fractional intervals), but if you do that with a long shutter speed + write time, you lose shots. Since the DJI camera is not designed for fast photography, they probably wanted to avoid the support pain of people complaining of lost shots, so limited it to a safe minimum of 2 seconds.
