Responsive Self Service Procurement Application: How to modify item types?

Content (required):

When using task "Create Noncatalog Request" with the Responsive Self Service Procurement Application, are there any possibilities to modify the item type values/field, if all of the types are not in use? Either to change the field to read only, or edit the name of the values, that the ones which are not in use would have, for instance, note "DO NOT USE"?

Seems that at least with the page composer it was not possible to edit the view in the Responsive Self Service Procurement Application.
