Norton sometimes sets my connection to Internet as 'Private' when it should be 'Public'

Hi, When I connect my pc to my Spectrum Cable/modem (no router), sometimes Norton sets my Network from “Public” to “Private”.
How do I force Norton or Windows 11 to Always connect to a network as Public?
(And not let me change it to Private unless I really mean to.)
Thanks

Go to settings - Smart firewall - Network. You can toggle between public and private.
