Revit cannot toggle display of representation axis

If a wall representation axis exists, linking the IFC into Revit will show the axis, but it will overlap with the body representation, and the user has no control to turn it off or on. This leads to ugly floor plans.

Revit should allow the user to control representation visibility.

Reproduce the reported case by linking an IFC with a wall representation axis into Revit and inspect how the axis overlaps the body representation. Determine the existing representation-visibility entry point, then verify that users can turn the axis display on or off and that floor plans no longer show unwanted overlap.
