Is it sure that the reflection is comming from the ambient ligth ?
If this, perhaps it is possible to shield this whit some bag or box,
but I can imagine the reflex is from the curved surface, and
in that case diffecult to reduce.

Perhaps it is possible to find a glazed tile, (wrong name pehaps, I mean
a keramic plate used in kitchen or bathroom) whit similar color and surface.
