If you're talking about implementation no, it's not. In order to start
a service with "start" argument it needs to be "enabled" in
/etc/rc.conf. It's nicely documented in various places like man 8 rc
or /etc/rc.subr.

What OP is looking for is 'onestart' and 'onestop' parameters. I was
looking for a solution to the same issue some days ago and found that
in /etc/rc.subr:

#       If argument has a given prefix, then change the operation as
follows:
#               Prefix  Operation
#               ------  ---------
#               fast    Skip the pid check, and set rc_fast=yes
#               force   Set ${rcvar} to YES, and set rc_force=yes
#               one     Set ${rcvar} to YES

Basically "/etc/rc.d/sshd onestart" will let you run sshd service
without enabling it in rc.conf (which also means it'll start at boot
time) yet it checks if sshd is not running already.

Hope that helps,

Karol
