How can I disable authentication in Elasticsearch

I am running Elasticsearch 7.14.0 and want to disable authentication completely. I set this settings:

xpack.security.http.ssl.enabled: false
      xpack.security.transport.ssl.enabled: false
      xpack.security.enabled: false

but the error I got is:

 [spec.nodeSets[0].config.xpack.security.enabled: Forbidden: Configuration setting is reserved for internal use. User-configured use is unsupported, spec.nodeSets[0].config.xpack.security.http.ssl.enabled: Forbidden: Configuration setting is reserved for internal use. User-configured use is unsupported, spec.nodeSets[0].config.xpack.security.transport.ssl.enabled: Forbidden: Configuration setting is reserved for internal use. User-configured use is unsupported]

it doesn't allow me to update these settings. What should I do in order to disable authentication and ssl?

Two questions;

Are you sure about that version?

Why?

sorry I mean 7.14.0 which is the version.

My Elasticsearch is running inside VPC which is a private network. It is sitting behind ALB (application load balancer). The authentication is setup in ALB layer so that ES doesn't need any authentication.
