No there isn't. The time and date are generated by the camera in display settings. If you switch it off there you'll no longer have it on the recorded image either. If you've too much text on the screen just limit your camera titles as best you can, disable the option for "week" in display settings so that the name of the day is not present and move it to an area of the screen that doesn't impede your image. You could also switch off the auto text size and make it smaller.
