How to make flat materials, that do not have shadows

Hello developers, I have a big problem that I wanted to see if you could help me solve

I have this model, which looks like this in substance painter.
but when I import it to roblox studio it looks like this:

Is there a way to make it not have those shadows?, and it is for UGC so I think changing the light settings is not an option

I have thought about removing all the normals from the object, maybe it could be a solution but I’m not sure, does anyone have any ideas?

I think you can just disable shadows in object properties for the model.

use future lighting instead of shadowmap

edit cuz i forgot to say the reason:
shadowmap has AO, future has it too but its hardly there because realism
