Yes, with the default dovecot.service file provided with 2.2.24:

$ systemctl cat dovecot
# /lib/systemd/system/dovecot.service
# This file is part of Dovecot
#
# If you want to pass additionally command line options to the dovecot
# binary, create the file:
#       `/etc/systemd/system/dovecot.service.d/service.conf'.
# In this file create a Service section and configure an Environment with
# the variable `OPTIONS'. For example:
#
#       [Service]
#       Environment='OPTIONS=-p'
#
# In the `Service' section you may also specify various other setting.
# If you have trouble with `Too many open files' you may set:
#LimitNOFILE=8192
#
# If you want to allow the Dovecot services to produce core dumps, use:
#LimitCORE=infinity
