Yes.
Use something like "
zmprov modifyAccount $user@$domain displayName $newName"
If you'll be doing many accounts at once it's best to have all the zmprov instructions in a single file and then feed it into the command. In other words, have a script that processes the csv file and comes up with something like
ma
user1@example.com displayName "User 1"
ma
user2@example.com displayName "User 2"
ma
user3@example.com displayName "User 3"
and then take that file and have zmprov read it:
zmprov < instructionFile.txt
it will be considerably faster.
ma is the equivalent to modifyAccount...and be ware the blank spaces
