Unable to delete Azure EventHub Cluster/Namespace/Entity/ConsumerGroup from Portal/ PowerShell/ CLI

Hello, also I have detected that if you are using Kafka, the property in consumers https://kafka.apache.org/documentation/#consumerconfigs_allow.auto.create.topics is true by default when using most common Kafka Clients libraries (such as spring-kafka), so the EventHub is recreating again and again. I would like to know if it is possible to disable this capacity in the namespace (in the same way that in a Kafka Broker) 

Best regards.
