I have seen the videos where they surrender. I have also seen the countless videos where they would clearly have surrendered if given a chance, but instead, they were blown up.

Sure; the same is true for humans shooting at you with machine guns and artillery. You don't always get a chance to surrender.

surrender is likely usually accepted when its possible, but with drones it is often logistically difficult because frontline is very wide now.

There are plenty of videos of russians fake surrendering. They are specifically instructed to put armed grenades on their body to kill those accepting surrender.
