You don't. Defaults are set in /etc/defaults/rc.conf, overridden in 
/etc/rc.conf. Unless you add the logic yourself in /etc/rc.conf, the 
environment is not looked at.
So this means a one-time edit of /etc/rc.conf:
if test -n "${SSHD_FLAGS}"; then
	sshd_flags="${SSHD_FLAGS}"
else
	sshd_flags="${sshd_flags}"
fi

Then start with SSHD_FLAGS="-o X11Forwarding=no" /etc/rc.d/sshd start

But this is specific for sshd, as it supports _flags. There's no generic way 
to do this.
