change dataclass to frozen at runtime

[jpanico]

I'm working with a dataclass that is code-generated by a tool I do not control:

@dataclass
class Concern:
    id: ConcernID

Note that the dataclass is not declared as frozen. I need this class to be frozen for the sake of Hashability, so I would like to modify the class at **runtime** to make it frozen. Is this possible?

thanks,

Joe
