How to have Multiple operators in a single namespace managing different clusters

Here I have two questions I am unable to do hope you can help on this?

  1. From the elastic cloud on kubernetes quickstart guide,I am only able to deploy operator in elastic-system namespace, how to deploy an operator with a single command in an other namespace other than elastic-system namespace?

  2. For example I will be having multiple clusters I want an operator for each cluster in a single namespace, How can I do that.

Answer will be really appreciable
