[Kuberay] Enabling/configuring autoscaling via kuberay-apiserver and/or ray-cluster Helm chart

Per github example, to enable autoscaling on RayCluster CRD we need to tweak autoscalerOptions and enableInTreeAutoscaling fields, however I can’t find similar fields either in kuberay-apiserver create cluster request payload, or in ray-cluster helm chart values. It also seems the config spec is inconsistent between those three (RayCluster, kuberay-apiserver requests payloads, ray-cluster helm chart). Is it intentional? Is it possible to enable autoscaling via apiserver/helm chart?
