Use allocation filtering - [Index-level shard allocation filtering | Elasticsearch Guide [8.5] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/8.5/shard-allocation-filtering.html) and/or [Cluster-level shard allocation and routing settings | Elasticsearch Guide [8.5] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/8.5/modules-cluster.html#cluster-shard-allocation-filtering)

Thank you for replaying,  
based on your share of data I use that.

```auto
PUT _cluster/settings
{
  "persistent" : {
    "cluster.routing.allocation.exclude._ip" : "XX.XX.XX.XX"
  }
}

```
