It wouldn’t be nearly as fast, but why would you not just stop the condenser pump so the helium stops cycling through, causing the freezing, instead of venting it off? Sure, venting it off would be faster, but in the lack of an actual emergency, you’d think you could wait like 5 minutes.

If it’s not an emergency, then you let the vendor follow the procedure they have in place for shutting down the magnet.
Edit:
For example: We had a flood in an MRI room. The vendor was called out to ramp the magnet down so that they could deal with the flood.
