[Observium] Disable Device Alerting

I have the new alerting in Observium setup for many events, including device down. However, over some of our wireless links I am getting false positives, so I turned up the ping retries to 3 times. Still happening, so I set the device down delay to 2. That has helped, however I am still getting the old school device alerting system emails. How can I disable those? I have port utilization disabled ($config['alerts']['port_util_alert']), etc. But I can't find anything in any docs or searches for disabling device down alerting in the old alerting system.

Any help is appreciated, thanks!
