Feature Request: Provide option to disable ipv6 listener in the nginxinc container for oidc-discovery

[cccsss01]

Many public clouds some w/ ipv6, many private clouds do not. Ipv6 standard is just now reaching the cis security standards, I think still in draft mode but many organizations will still take time to reach the new security standard.

Shouldn't this be done at the k8s cluster level?
