I wonder to what extent either side is worried about the firmware on the drones. Somehow getting tampered-with firmware onto the drones that your enemy is using seems like it would be valuable.
I suppose it could be used sparingly but Ukraine would have no way of knowing when to use it. Perhaps a Bluetooth or whatever else the drone has on board "keep away" beacon for vips.
The real enemy is QA. Don't want it misbehaving during a virtual test flight.
