Is there a way to restrict specific inventory items from appearing in the hosted catalogs

We have items maintained in Product Information Management (PIM) that are enabled as internally orderable items and published in a hosted catalog within Self Service Procurement (SSP). These items can be added to the shopping cart and submitted as internal requisitions, which in turn generate transfer orders.

We also have an integration with RF-SMART, which allows users to initiate these transactions via handheld devices. The transactions are then transmitted to Oracle Fusion Self Service Procurement for processing.

There are specific items that we would like to exclude from the hosted catalog UI, preventing users from manually adding them to carts via Oracle. However, these items still need to remain purchasable and fully transactional through RF-SMART. The goal is to ensure that these items are only accessible through RF-SMART workflows, not through direct interaction in Self Service Procurement UI.
