Kafka - Setting value for `replica.fetch.max.bytes` through an environment variable

Hey all,
I am using kafka in docker and want to set value for replica.fetch.max.bytes through environment variable, could not find a list of supported env variables in docs. Can anyone help me with the correct variable please?

Which image do you use?

confluentinc/cp-kafka:6.1.1

https://docs.confluent.io/platform/current/installation/docker/config-reference.html#confluent-ak-configuration

Try
REPLICA_FETCH_MAX_BYTES
