Questions about maxscale 2.21 version

Hello, I use maxscale 2.21 version and I have a question. I am testing by linking maxscale and auroramysql, and I entered the instance endpoint in the current setting. I have a few questions in this regard. 1. Is there a feature that uses instance endpoints in the settings and can automatically find and add additional ro nodes? 2. We believe that using instance endpoints cannot automatically detect new nodes, so we want to test by putting the cluster endpoints in the settings. However, after entering the cluster endpoint, I cannot find the master ID when I proceed with failover, so I think this is a jdbc problem, so I would like to change jdbc. I want to try using aws-jdbc-driver but I don't know where to change that setting. Can I change the jdbc-driver myself and use it? If you can, please tell me how
