QUESTIONIs there a way to hide/restrict the Nintex Forms button on the ribbon?
ANSWERAn access control setting for Nintex Forms Designer via site settings (like "Allowed workflow designers" feature for Nintex Workflow Designers) is not a currently planned feature. A feature request can be submitted via https://nintex.uservoice.com
Restrict Access to Nintex Forms designer
To restrict access to the designer, grant users "Contribute" permission.
