Is it possible to change the retention settings for /aws/containerinsights/cluster-X/performance log groups

version: v2.1.1-eksbuild.1
add-on for eks: amazon-cloudwatch-observability

Is it possible to change the retention setting for performance logs using the add-on's configuration values?

I was able to change the retention for application, dataplane, and host logs using log_retention_days,
for example - application logs:

containerLogs:
  fluentBit:
    config:
      extraFiles:
        application-log.conf:
          [OUTPUT]
            Name cloudwatch_logs
            Match   application.*
            region $${AWS_REGION}
            log_group_name /aws/containerinsights/$${CLUSTER_NAME}/application
            log_stream_prefix $${HOST_NAME}-
            auto_create_group true
            log_retention_days 90
            extra_user_agent container-insights

Also, i do not understand how the performance log stream gets created. I do not see how we can disable its creation, nor what writes to it.
Can someone explain please?

any news on that, i'm looking for a way to define the log_retention without providing the full conf file
