Options to Deploy Kafka on Kubernetes

We are using following helm charts from Confluent.

But, the above helm charts are deprecated by confluent as they noted in below

Confluent recommends to use CFK (Confluent for Kubernetes) way of installing Kafka on Kubernetes

Do we have any other alternatives to deploy Kafka on kubernetes which won’t require paid subscription ?

We can use helm charts (above) for now but as confluent deprecated and not updating them, Wondering how other are deploying Confluent Kafka Community versions in kubernetes environment ?
