[2] Stop and turn OFF auto-start setting for a service if you don'd need it. (it's smartd as an example below)
[root@dlp ~]#
systemctl stop smartd

[root@dlp ~]#
systemctl disable smartd

[3] There are some SysV services yet. Those are controled by chkconfig like follows.
[root@dlp ~]#
chkconfig --list

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

netconsole      0:off   1:off   2:off   3:off   4:off   5:off   6:off
network         0:off   1:off   2:off   3:off   4:off   5:off   6:off

# for exmaple, turn OFF auto-start setting for netconsole

[root@dlp ~]#
chkconfig netconsole off
