DevExpress' Ribbon bar: how to disable and hide “Full Screen Button”-Collection of common programming errors

Windows 7 SP1 (x86) + Delphi XE2 + DevExpress 2013.1.2 (VCL) + TdxBarManager + skin “Office2013White”.

How to disable and hide “Full Screen Button” in design-mode and/or runtime-mode (screenshot of button):

I tried to find it in resources (.pas), then tried to edit skin by dxSkinEditor (.skinres), but failed.

Thanks in advance.
