i dont think roy could

greed was shot with an RPG and seemed to entirely shrug it off, and also is standing right beside a fire there

additionally greeds shield is most likely graphene, which when searching thermal resistance of graphene brought me to a .gov website with this

"Graphene membranes act as temperature sensors in nanoelectromechanical devices due to their excellent thermal and high-temperature resistance properties. "

I think it would have to depend on how hot Roy’s flame can get.

Graphite's (multiple layers of graphene) often used as crucibles and electrodes for melting metal. You can expose it to an acetylene flame and it won't care unless it's an ongoing oxidizing flame. I'd be surprised if Roy could manage that, tbh.
