Hi Rash,
Please go to system role and click to create new Role and give name as system administrator, Under this Role defined all views and marked them except uncheck\ unmark incident view, After this You may able to create multiple users and then assign them under System administrator Role. Then These user will be able to see system view (Agents, server’s, policies etc.) & incident ID but not contents mails of those DLP incidents.
in simple way just uncked incident view in general tab of DLP role definition and then your role wont have any view on DLP incident.
