The fact of the matter is, there is no private unseen community string. The config file tftp'd to the modem from the cmts bootstraps the modem, so it contains all the information needed for the modem to run, including respond to snmp requests. ABM is trolling everyone with misdirection for shits and giggles.
Think about it, if there was some magical private community string (which isn't even defined in IOS) that was sent during a FW update or some other magical time, wouldn't that same technique be used to set every other property such as speeds, filters, etc.
Community strings are defined in the config, plain and simple. There may be x509 certs used in place of community strings for snmp query, but that isn't a string.
If you cant scan and you exhausted all options, your cmts implements ACL, which prevents any CM with a certain MAC or within an IP range to do snmp and the likes.
Quit bullshitting people ABM.
