Turn on Forms for a group

You could try group-based licensing 

“You can assign one or more product licenses to a group. Azure AD ensures that the licenses are assigned to all members of the group. Any new members who join the group are assigned the appropriate licenses.“

“When a product license is assigned to a group, the administrator can disable one or more service plans in the product. Typically, this assignment is done when the organization is not yet ready to start using a service included in a product. For example, the administrator might assign Office 365 to a department, but temporarily disable the Yammer service.”
