DynamoDBPersistenceService - Not ready to store

I’m using openHAB 3.1.0 with an OpenJDK 64 Bit v11.0.12. I added different KNX Things and after creating Items I get warnings in the openhab.log:

2021-09-11 10:29:55.222  [WARN]. [.internal.DynamoDBPersistenceService] -  Not ready to store (config error?), not storing item SomeItem

In Settings I set Persistence to RRD4j. In Settings “DynamoDB Persistence Service” is not configured. I don’t like to use it at the moment.

What can I do to suppress the log messages?

Uninstall the add-on? It might be listed under Amazon DynamoDB
