I'm trying to use kafka-avro-console-producer 5.4.0-ccs without to autoregister the schema. I tried with:
--producer-property auto.register.schemas=false
and
--property auto.register.schemas=false
But it's registering the schema anyway. The property seems correct: https://github.com/confluentinc/schema-registry/blob/a0a04628687a72ac6d01869d881a60fbde4177e7/avro-serializer/src/main/java/io/confluent/kafka/serializers/AbstractKafkaAvroSerDeConfig.java#L54
it seems the property is auto.register
for the CLI instead of auto.register.schemas
. I found it in the code but it may change in next versions since and it isn't documented.
