Sure, 

1. Have your router block it, so your server doesn't even see it.
2. Use secure-zone txt records
3. configure your DNS server (if possible, you didn't tell us which one
you use) to not allow this. 
4. Don't give the internet a NS record that points to this nameserver.

You server is not generally going to be queried by the internet, unless
another server told people that it was authoritative for the domain.

If you want a server to respond to queries from the internet, you
register it when you register you domain.
