Prevent Dump1090 from feeding data from a specific aircraft

#1
Let's say I have a Raspberry Pi running Dump1090 Mutability feeding multiple sites.
A local police chopper with ADS-B on shows up regularly, I am the only one feeding the data and I don't feel comfortable doing so.

Would it be possible somehow to "ban" that aircraft data from being feed from my Raspberry? Some kind of Dump1090 "blacklist"?

Thanks.
