The UCoC Enforcement guidelines ratification vote launches on 7 March 2022 and runs through 21 March 2022. (More info on Meta)
This will be a global election which means a voter list needs to be generated. We last did this for MCDC elections in September - T291668: Create voter list for MCDC 2021 SecurePoll elections.
I am happy to follow the instructions on Wikitech though will need technical support for the creation of the new tables and script required. This was done by @Reedy in https://gerrit.wikimedia.org/r/c/mediawiki/extensions/SecurePoll/+/723316/ last time.
