In "season 1" of Lost Ark in Korea, there was a weapon vendor in Changhun that had weapons that you could needed the plate for.
As of right now, NA/EU does not have this weapon merchant.
Vendor trash has normally an blue bag icon, but this item does not, meaning it can be used elsewhere. Where to use it is the real question.
Here you can see the item as a part of a weapon:
