Use your own custom modded drone to drop a small net made of fishing line on top of the invader. Fouls the props.
That could do it!
Then again, the “eagle kills drone” from Oz on youtube rekindles an interest in falconry.
Great video... especially the quiet pathetic whine of the little motors churning on the ground. Not quite the lamentations of their women, but crying pajama boys will serve in a pinch.

The net part was my idea too, a lightweight net packed into a shotgun shell, weighted around the edges so it has some throw weight and will open to a circle. Like the round cast nets used to get bait fish.
A lot of neighborhoods do not lend themselves to shot, steel or otherwise.
