There's clothing you can wear.

Build a giant animatronic ring doorbell camera with binoculars that peers into your neighbors homes, wearing a "Hello, my name is Big Brother" sticker?

A little drone with a laser?

Aside from asking nicely or doing it yourself, uhhh... do it with magic?

I can't think of anything, that's kind of the options isn't it? Buy your neighbors switchbots or reolink cameras as a gift? Them switching by choice is persuasion... forcing them to switch without giving them a choice is vandalism. I can't fathom a 3rd category, unless you can like... sue the hell out of amazon and force a recall, but pretty sure the legal system doesn't work that way.

Lasers can break a lot of cameras. Idk strength but even multiple laster pointers were enough to take out some cameras. More powerful ones you get into eye protection problems though. One refraction and you can get permanent damage and you need specialized protection for your eyes to be sure as it's different wavelengths of light than welding type protection that is cheaper because it's more mass produced.
