STemWin and user DMA2D operations on STM32F746 Discovery

Hi,
I got an application that uses STemWin to display a GUI on STM32F746 Discovery LCD.

The STemWin initialization is this
**
     GUI_Init();
     /* Activate the use of memory device feature */
       WM_SetCreateFlags(WM_CF_MEMDEV);
     /* Automatic use of multiple buffers */
     WM_MULTIBUF_Enable(1);
**

My question is this, can the DMA2D controller be used from an application at user's discretion to directly write on a LCD memory area (that STemWin does not use to draw anything in it), or the DMA2D is used exclusively by emWin core on STM32?

Christos
