Is there a way to set default compatibility level for Confluent Schema Registry?

Question

We are planning to use the Confluent Schema Registry within our Kafka ecosystem. We use the schema registry image from Confluent and run it within our Kubernetes platform. The default compatibility level is set as BACKWARDS, however, we would want to set it as FORWARD_TRANSITIVE as soon as the schema registry starts.

I know this can be achieved by making a REST API call to update the global compatibility level, but is there any environment variable that can do this, without making the REST API call?

Thanks.

You'd set schema.compatibility.level config, yes

This can be set in a Kubernetes manifest or as an env-var directly
