Another use case for the implied ability to disable a datasource simply by adding `linux_cpu_snmp.disable=true` and having the DS no longer apply to the device.
If you remove auto properties, they’re likely to resurface the next time propertysources run. System properties are the same way. To truly prevent this, you either need to modify the device so that it doesn’t match the AppliesTo or modify the AppliesTo so that it no longer matches the device. The former is the better option because you simply need to remove in LM the SNMP credentials from that device.
Unfortunately, if it’s inheriting snmp.community from a group that it’s a member of, you’ll have to do some property inheritance gymnastics to get it not to inherit.
