Its possible to save it. You can cut off the sacs with a razor, just be super careful not to cut any of them open. It's better to cut into the stem than into the sac. Even if you cut a stem completely off you can literally tape it back on and it will probably heal.
You may still get a few seeds but the harvest will be good. The seeds will also be feminized, but genetically speaking have a higher chance of turning hermie on you.
