The precise answer depends on what version of FreeBSD you're running,
which you failed to mention.  You can work it out from the FreeBSD FAQ
entry titled "I made a mistake in rc.conf, or another startup file,
and now I cannot edit it because the filesystem is read-only. What
should I do?", which you can read at:
