Downward sensors

Hi guys,
I fly a Mavic Air 2. I use the DJI Fly app, and do a lot of flying over surf. I’ve read it’s safer to turn off the downward sensors on the MA2 when over water. Is it possible by turning off the obstacle avoidance within the fly app? Or does this not effect the downward sensors? Is the only way to cover them with gaffa tape?

How close are you flying to the surface of the water?

It varies every flight, but generally the lowest would be a couple of meters.
