Hi @sblomberg
If you want to use ACF in your project but doesn’t want it to be changed from the backend, I suggest you register the fields trough PHP code instead. That way the field group won’t shows up on the editor page so the other collaborator won’t accidentally changed it. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/register-fields-via-php/. It will be a little bit difficult when you need to modify it, though.
If that doesn’t fit your needs, you can always submit a feature request by opening a new ticket here: https://support.advancedcustomfields.com/new-ticket. This will make sure that your request is passed directly to the plugin author.
Thanks 🙂
