Describe the issue: Is it possible to perfrom the restart with no replicas?

like:
OST /_snapshot/my-opensearch-repo/my-first-snapshot/_restore
{
“indices”: “opendistro-reports-definitions”,
“ignore_unavailable”: true,
“include_global_state”: false,
“rename_pattern”: “(.+)”,
“rename_replacement”: “$1_restored”,
“include_aliases”: false

"no_of_eplicas": None

@GuyS After testing this locally with no security, I was able to restore with 0 replicas using the following syntax:

POST /_snapshot/my-opensearch-repo/my-first-snapshot/_restore
{
  "indices": "opendistro-reports-definitions",
  "ignore_unavailable": true,
  "include_global_state": false,
  "rename_pattern": "(.+)",
  "rename_replacement": "$1_restored",
  "include_aliases": false,
  "index_settings": {
    "index.number_of_replicas": 0
  }
}

Hope this helps
