You can use the remove_constraint method:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Triangulation_2_ref/Class_Constrained_triangulation_plus_2.html#Function_void_remove_constraint6Vertex_handle_va+_Vertex_handle_vb9;

If you want to get all previously inserted constraints, have a look at 
constraints_begin():
