Force MSAA off?

So I'm having trouble with a low budget game called Tokyo Xanadu eX+. It looks like the game forces MSAA or that's my best guess since there is no depth buffer access. Is there any way to force MSAA off through nvidia drivers or something like that?

Can anyone troubleshoot with me how to get depth buffer working in this game? It's a PSVita port so MXAO and decent looking DoF is a must for this type of game.
