Yes, just fire up the Manager running on the same release as the 406, and do the regular File | Advanced | Upgrade, which will find the expansion module and offer to downgrade it.
Usually, the customer has the version of Manager that was used to set up the system, otherwise you'll need to download the correct bin files and change your working directory.
