There might be several ways to override settings.
I do it with a sessionCustomizer.

in persistence.xml :
     <property name="eclipselink.session.customizer" 
value="aurora.MySessionCustomizer"/>

then an ordinary java class:

public class MySessionCustomizer implements SessionCustomizer{
   public static volatile String jdbcpwd;
   public static volatile String dbfilename;
   public static volatile Integer dbinternalcacheKbyte = 32768;

   @Override
   public void customize(Session session) throws Exception {
       session.getLogin().setPassword(jdbcpwd);
       session.getLogin().setShouldTrimStrings(false);
       session.getLogin().setQueryRetryAttemptCount(0);            
session.getLogin().setConnectionString("jdbc:h2:~/"+dbfilename+";CIPHER=AES;DB_CLOSE_DELAY=-1;CACHE_SIZE="+dbinternalcacheKbyte+";MODE=HSQLDB");        


   }

}
