What right to privacy?
To the extent that you have a right to privacy, you have to be in a private space and that right extends only to the extent that you are not observable from a public space. For example, you have a right to privacy in your bedroom if you close the curtains.
Any such space is almost certainly indoors where drones are unlikely to be an issue.
You can’t break other people’s stuff
You just can’t. If you do it negligently, you have to pay for it. If you do it deliberately, you have to pay for it and you’re committing a crime.
What you can do
Drone use is increasingly regulated. If they are breaching the regulations, report it to the regulator.
It’s possible that you could succeed in a nuisance suit if you can identify the operator.
