dynamic=false on mapping

[geogeim]

I would like to disable dynamic mapping at the type level. I see that there's an undocumented option on @EsEntity anotation but it doesn't work, it sets dynamic on the query parameter and that causes an error when creating the mapping on the index:

Elasticsearch TRACE: 2021-02-20T14:57:59Z

...
    }
  }
  <- 400
  {
    "error": {
      "root_cause": [
        {
          "type": "illegal_argument_exception",
          "reason": "request [/search/_mapping] contains unrecognized parameter: [dynamic]"
        }
      ],
      "type": "illegal_argument_exception",
      "reason": "request [/search/_mapping] contains unrecognized parameter: [dynamic]"
    },
    "status": 400
  }
