I have a question about the number of replicas for system indices (Elasticsearch 7.5.x).

Standard number of shards = 1, number of replicas = 1.

Is it possible to change the number of replicas for system indices?

For example:

```
PUT /.kibana_1/_settings
{
    "index" : {
        "number_of_replicas" : 2
    }
}

```

return:

```
{
  "acknowledged" : true
}

```

but it doesn't work...

Any idea?
