The UUID usually already gets recorded and displayed:

# lsblkj -f --until "2020-01-09 22:00:00"
NAME                             FSTYPE      FSVER LABEL UUID                                   FSAVAIL FSUSE% MOUNTPOINT
sda                                                                                                            
├─sda1                           xfs                     78524ad6-6445-4bb6-840b-194871231274   
...

(It's also capturing something simple for mountpoint when it can, but so far that's
only visible with journalctl.)
