Does contract administrator role ensure access to setup and maintenance for enterprise contracts

Summary: We have created a custom role by copying the Supplier Contract Administrator role and without removing any privileges from the seeded role. But with that role, the users don't seem to have access to Setup and Maintenance tasks. They see the Setup and Maintenance option but when they go in no tasks are visible.

When we added the Application Implementation consultant role, the users get access to Setup and Maintenance area and the tasks, but all the modules are enabled for the users. They get access to all implemented modules and the related setups.

Is there a way to restrict a users access to Setup tasks for only Enterprise Contracts area and not other areas?
