Nope this is not a hook this comes with the theme itself and you cant edit the whole design only the Texts, Like "Total Topics, posts etc" thats what you can edit i've tried that before, Otherwise if you don't like it just disable it and it'll not show anymore.
This is Gridlock and its into The donator section, its not that Theme tbh, Not cool to have a Forum and Every section has an image, which the forum will look ugly & Busy
But i guess Chris's Answer is enough.
