Make forms read only just for a specific group of users

Summary:

Is there a good way to make a set of forms (I have about 15 in a folder) to display as read-only for a specific group of users.

Content (please ensure you mask any confidential information):

The users have write access to all data but should only be able to see the output from this process not be able to edit it.

Duplicating all the forms and setting them to read only and hiding from all other users will work, but it feels like there should be a better solution.

Setting a form folder security access to read only does nothing to prevent those users from having write access to the forms.
