Alternative of Helm charts

As I read that we are not supposed to use Helm charts anymore and instead we should use Confluent for Kubernetes(CFK).
One question I have, in that case how we are going to manage different values for different envs ? Not much into cluster setup so dont have much idea.
Could anyone help with some docs or links regarding best way to manage CFK for different envs (Dev,ST, AT, Prod etc) without Helm Chart.

Operators aren’t a complete replacement for Helm. They are a replacement for manually defining Deployments, Services, Secrets, Ingress, etc.

You can still use Helm with CustomResources
