In our environment when we tried scaling up the node, so Eck operator creates new node as Stateful Set which is default behavior but, we want it as a Deployment.
Could anyone help me where to change in the template file or is it supported by Eck operator.
It is not possible. I assume you are trying to create Elasticsearch NodeSet. If so it is stateful by nature, Elasticsearch is sateful application and it must be done with Statefulset.
