You can do this by disabling the fringe.  The manual says:

Doing this means that code is sometimes overlayed with "=>" and breakpoint
icons display in the margin instead of the fringe (this cause the code to
shift to the right).

Why would you want to do this?  What problem do you see with the triangle in
the fringe?
