Data Prepper 2.4 Kafka source

Hello,
Is it possible to specify SSL CA cert for Kafka source in Data Prepper 2.4?
We have Kafka cluster to read from, with SSL and without Authentication. All Kafka certs are signed with our internal CA, so we need to put root CA certificate in the truststore, or somehow specify it to use on the consumer side. However, I didn’t find any options for that in the Source plugin configuration.
