How to remove a default configuration in the elasticsearch.yml file?

[wangxr1985 (xinrong wang)]

In the elasticsearch.yml file of the pod created by ECK, there is a default configuration as follows:

xpack:
    security:
        authc:
            realms:
                file:
                    file1:
                        order: -100
                native:
                    native1:
                        order: -99
            reserved_realm:
                enabled: "false"
        enabled: "true"
        http:
            ssl:
                certificate: /usr/share/elasticsearch/config/http-certs/tls.crt
                certificate_authorities: /usr/share/elasticsearch/config/http-certs/ca.crt
                enabled: false
                key: /usr/share/elasticsearch/config/http-certs/tls.key
        transport:
            ssl:
                certificate: /usr/share/elasticsearch/config/node-transport-cert/transport.tls.crt
                certificate_authorities:
                    - /usr/share/elasticsearch/config/transport-certs/ca.crt
                    - /usr/share/elasticsearch/config/transport-remote-certs/ca.crt
                enabled: false
                key: /usr/share/elasticsearch/config/node-transport-cert/transport.tls.key
                verification_mode: certificate

If I make the following configuration in the k8s yaml file, I can override it with my own specified values.

spec:
  version: 7.11.1
  nodeSets:
  - name: master
    count: 3
    config:
      node.master: true
      node.data: false
      node.ingest: true
      xpack.security.transport.ssl.certificate: /usr/share/elasticsearch/config/my_tls.crt
      xpack.security.transport.ssl.certificate_authorities: /usr/share/elasticsearch/config/my_ca.crt
      xpack.security.transport.ssl.key: /usr/share/elasticsearch/config/my_tls.key

But if I want to remove these configurations, how should I set it?
