Elasticsearch Helm chart: Set -Dlog4j2.formatMsgNoLookups = true in jvm.options

I was trying to update Elasticsearch cluster in AKS using helm chart. I wanted to set it up with option -Dlog4j2.formatMsgNoLookups = true in jvm.options file in the pods but using values.yaml file, I can only add it in /usr/share/elasticsearch/config/log4j2.properties. I see only option to add it as below:

esConfig:
#  elasticsearch.yml: |
#    key:
#      nestedkey: value
  log4j2.properties: |
    -Dlog4j2.formatMsgNoLookups = true

Please let me know if the above setting should be enough for log4j vulnerability primary fix and how to add the parameter in the jvm.options file directly? Are we getting a new updated chart soon?

Anyway, I’m using it for now, so thanks!
