Listbox Virtualization with ScrollViewer.CanContentScroll="False"?

Looks like listbox with ScrollViewer.CanContentScroll="False" does not support virtualization. And if i set the CanContentScroll to True, scrolling is not smooth but does support virtualization (hopping by item).  Is there any trick to make listbox virtualized when CanContentScroll is set to False?
 

Thanks.
