you can disable the monitoring before your update begins and enable it again 
when it stops:

        1.) monit unmonitor exim
        2.) perform exim update / deploy application
        3.) monit monitor exim

If you need to delay the implicit restart if the process stopped, you can 
override the default action:

check process exim with pidfile /var/spool/exim/
        if does not exist for 10 cycle then restart
