don't know about quick connect bars, but Gear Guard sounds like the Rivian Sentry Mode. The following text is from the Rivian site:
Our remote monitoring system features a cut-resistant locking cable that wraps around your gear and plugs into the bed wall – connecting directly into the vehicle security system. Remotely monitor your gear through the Rivian app and receive instant alerts if the system senses an interruption. A camera in the bed also monitors your gear."
