glossy surface when importing certains meshes I'm trying to import into Blender 2.9 some .fbx models exported from a 3D software called Noesis.
The issue I'm facing is that the models, once in Blender, look somewhat covered by a glossy/metallic surface, both in solid mode view and in material preview.
This is what I mean:

while this is what I would expect/like:

This second picture is done removing the material assigned to the object, to understand if the issue was related to the material itself, and indeed it looks so.
This last picture shows (on the left) the object as shown on Noesis (and how I'd like it to be), and on the right how it looks on Blender. As you can see, that glossy feel is there also in material view.

I tried importing the object in an online FBX viewer, and it looks glossy too, so I'd say it's not a Blender problem.
Do you know what it could be, and how I could fix that? (assuming that I can't edit any parameter during the export on Noesis)
thank you
blender file:
Check the Material Viewport Display, the Metallic value is 1, bring it back to 0:

Also, the material is 100% metallic, bring the value to 0 if you don't want any metallic effect:
