How to disable long press triggering right click context-menu on Gnome3.18 desktop

Question

In Gnome3.18, a feature is introduced：

Context menus can now be accessed using a touch screen — to activate, just press and hold.

However, I would like to disable such feature on desktop. Anyway I can disable the long press feature, or even remove the context-menu?
