I'm not sure if it's the best/easiest way, but in the past I've used
udev rules with ENV{UDISKS_IGNORE}="1":

You could instead put the thing in fstab with a "noauto" as one of its
mount options. Then it wouldn't be mounted by the system at boot, nor by
udisks.
Obviously you can stop all automounting by stopping the udisks2 service
(and maybe masking it). That leaves it installed but not running. Some
software wants it to be running though.
Although it is udisks2 and udev that are facilitating this, I thought it
only happened inside a desktop environment. Though your example of
/media/root/UUID suggests not. Anyway, some ideas for desktop
environments:
