Unable to perform redwood customization to remove New Supply Request access

We have created a custom supply chain orchestration role, with the requirement that users assigned to this role should not have access to the following navigation path:
Navigator > Supply Chain Execution > Supply Orchestration > Supply Requests > New Supply Request

We have already removed functional access to the "New Supply Request" button using privileges, so that when users click it, they are redirected to the home page. However, the client’s expectation is that the button should not be visible at all for this role.

As this is a redwood page, we considered using VBS customization, but we could not find the relevant fields or regions to hide the button using VBS.
