The propagation of Dyakonov surface waves was numerically investigated for the interfaces of two biaxial anisotropic media. Variation of the propagation direction changes the field energy localization from one of the partnering media to another. It is possible to find a specific propagation direction, which is characterized by the strongest energy localization in the boundary plane. This direction corresponds to the central angle of the angular existence domain. On the other hand, variation of the components of the media permittivity tensor, including the introduction of gyrotropy, changes the possible propagation directions, which is a potential way to control surface eigenmodes.
