Vishal, b.producer.acks should work, as can be seen in the following unit
test with similar producer property "client.id":

https://github.com/apache/kafka/blob/6b905ade0cdc7a5f6f746727ecfe4e7a7463a200/connect/mirror/src/test/java/org/apache/kafka/connect/mirror/MirrorMakerConfigTest.java#L182

Keep in mind this should be configured for the target cluster, and it might
not take effect until the workers finish rebalancing.
