Service Catalog - Hide "Requested For"

On a previous thread there is a way to hide the “requested for” and make the requester field non-editable. However, this custom CSS hides it for all items. We want to hide it for certain items.

The code in question:

/* Hide Requester field label */
body[page="catalog_item"] #side-modal #side-modal-content .place-request-container .control-label label
{
    visibility: hidden !important;
}

/* Hide Requester email address field */
body[page="catalog_item"] #side-modal #side-modal-content .place-request-container .control-element input {
    visibility: hidden !important;
}
