IDK how to export hard edges from maya into smoothing groups in max. Maybe google can help there.
But for this specific model, in your last pic, hit autosmooth in the red circle by a low angle number like 5.

In most game pipelines you need hard edges only on uv borders.

Cause of this i would ignore the hard edges on export and run a sript to create smoothing groups from uvs in max
There are serveral out there.

Maya doesn't do smoothing groups so they can't be exported.

There are some smoothing group generation scripts available - not always 100% reliable though.

Failing that.. Can you derive creasing from hard edges in the opensubdiv modifier? I've not tried
