To disable these service alerts in the Direct Admin control panel, you can simply edit the file services.status at /usr/local/directadmin/data/admin/

#GNU nano 2.0.9 File: /usr/local/directadmin/data/admin/services.status directadmin=ON dovecot=ON exim=ON httpd=ON lfd=ON mysqld=ON named=ON proftpd=ON sshd=ON

You now should no longer receive these updates from the selected services.
