How to set tcpKeepAlive time for each connection.

Hello.

I am creating a client that uses MariaDB Connector / J. This client connects multiple connections. I want to change the time of tcpKeepAlive for each connection. The tcpKeepAlive time is specified in the properties tcp_keepalive_time, tcp_keepalive_interval and tcp_keepalive_probes and cannot be changed when connecting.

Question

1. Is there a way to set different times for each connection using tcpKeepAlive?

2. Is there a method other than tcpKeepAlive to detect disconnection at different times for each connection?

3. If it is difficult to detect disconnection at different times for each connection using the above methods 1 and 2, how should the client connecting to the database detect the disconnection?
