I think by default they are set to spray on every 3rd screen clean, iirc that can be coded to a higher number say 5. Also quickly spraying the windscreen a few times in quick succession without triggering the screen wipe will not trigger them.
You can pull a fuse also, check the fuse box in the glove box for the card somewhere in there iirc.
I think you might also be able to disconnect the pump to them but never looked into that.
