I would say we really do not know.
It has been suggested that B. had a short trunk like a tapir,
and the nasal enlargement was to provide attachment points
for the muscles and ligaments. (the nasal openings of animals
with trunks, such as elephants, are often high on the face)

No, as the nasal openings are in the bump.
The bumps on giraffes are small horns, similar to the larger
horns on antelope.
> Could those Brachiodudes be submerged in water to their nasalthingies?
No. The would not be able to breathe when that deep, due to the
*immense* water pressure.
The peace of God be with you.
