Locking down a shared CardDAV account accross multiple iPhones

[jmichels]

Has anyone had any luck with preventing multiple users from editing or adding to a shared CardDAV account that syncs contacts across multiple iPhones? I was able to use Jamf to push a set of contacts out to our iPhones through a gsuite cardDAV account but I would love to be able to lock it down for the end users of the phones. This way I can make changes to the contacts and have all users see the changes without everyone and their mom being able to make changes as well.

Any ideas would be super helpful. Thanks!

I would like to do this as well.

Everything works great except that all can edit or add to the shared carddav account.

Has anyone found a way to prohibit end users from modifying contacts? I'm still toying with this. My knowledge of iOS - Managed & Automated Contacts is limited. Heres what I'm using to test. Works great - besides end users ability to edit contacts which syncs across all devices with the configuration profile.
