If you disable this option, the following message appears:

NoteIf you disable Show/hide UI, this UI is NOT visible for future import operations. To restore UI visibility, hold down the SHIFT key during import.

Hold the “Shift” key of your keyboard to display the FBX UI.

Note The Maya FBX Plug-in sets this option independently for import vs. export plug-ins. This means that if you want to hide the FBX UI for both the FBX Importer and Exporter, you must set this option separately in both UIs.
