How to sync deck while keeping user progress local

My parents started learning foreign language and Im making them deck. Right now I basically login into their accounts and do changes and add cards, repeating same actions 2 times. How I could make it so that I only need to manage 1 deck and changes get updated in their devices? Easiest I could think of would be just somehow use single account, sync deck but keep user progress locally without syncing it to other devices.

AnkiCollab - A free collaboration Platform - AnkiWeb

AnkiHub - AnkiWeb → Paid subscription (5$/month)

The two above, idk if you can make private decks to share only with your family

Special Fields - AnkiWeb → You would be able to update their content without changing progress
