Apache Flink

Hi all, Is there any way to generating only error logs in Job Manger and Task Manager when there is any error?  I tried to set this <http://log4j.logger.org|log4j.logger.org>.apache.flink=ERROR in conf directory for Flink. But I still see INFO logs through Web UI.

2023-10-16 12:53:44,883 INFO  <http://org.apache.flink.kafka.shaded.org|org.apache.flink.kafka.shaded.org>.apache.kafka.clients.NetworkClient [] - [AdminClient clientId=te_lab_group_merged_label-enumerator-admin-client] Node 2 disconnected.

We are are using application mode and deployed in Kubernetes Cluster. When I see logs of of Kubernetes pod I see above message, My goal is to stop this messages.
