I don't play DC Universe but I'm pretty sure it isn't a DX11 game. If it's not then Windows 7 isn't forcing the game to run in DX11 because the game isn't DX11 capable.
"If" the game is DX11 then there should be a setting in the game options to "downgrade" to a lower DX mode.
Here's a list of current and upcoming games that suport DirectX 11: List of games with DirectX 11 support - Wikipedia, the free encyclopedia
DC Universe isn't one of them.
