How to detach dock hardware on new surface.

I received a new Surface laptop and it came with what looks like a docking station attached to the bottom.  I am strggling to figure out how to detach it.  Any tips would be appreciated.  It is convenient but it takes away from the overall Thin profile that I bought it for.  Does any one even know what it is called or has seen it before?  I cannot seem to find anything on line.
