How to delete mariaDB's specified connection_name for multiple replication

I have several replication settings on mariaDB(latest:10.1.8). Please make sure that I'm using Multiple replication not a legacy Single replication.

I've added some settings with CHANGE MASTER "blah" TO command. Now I'd like to remove just one of them from show all slaves status.

mysql -e "show all slaves status\G;" | grep "Connection_name\|Running"
              Connection_name: 
             Slave_IO_Running: No
            Slave_SQL_Running: Yes
              Connection_name: asi.exapmle.com
             Slave_IO_Running: Connecting
            Slave_SQL_Running: Yes
              Connection_name: bee.exapmle.com
             Slave_IO_Running: Connecting
            Slave_SQL_Running: Yes
              Connection_name: dild.exapmle.com
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes
              Connection_name: datr.exapmle.com
             Slave_IO_Running: Connecting
            Slave_SQL_Running: Yes
              Connection_name: db.exapmle.com
             Slave_IO_Running: Connecting
            Slave_SQL_Running: Yes
              Connection_name: nop.exapmle.com
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes

How can I delete only db.exapmle.com from this replication list without getting a effect to other replications?
