Constrain pathfinder nav paths to X and Y axis

Is it possible to force Nav paths to be constrained to the X and Y axis only? The result being only 90 degree turns on the plotted paths (following the compass cardinals). I don’t want any angles below 90 in the final path.

If so, how do I configure this? I’ve been playing with agent radius and cell size etc, but can’t seem to eliminate angles.

Any ideas?
