You can have all sorts of fun in “Advanced Options > Advanced Rendering Options.” The relevant settings for these are listed under “Rendering control.” I don’t believe you can disable mipmaps entirely, but using either Nearest Neighbor or Trilinear (according to preference) with 16x anisotropy (no point in going higher) will get rid of the obvious detail lines.
Note that nearest neighbor also affects things like lights and shadows, which might look pretty strange. The game is built with filtering in mind.
