CatchAll with hash = False?

[hemna]

Is there a way to declare a CatchAll member variable and specify that it's not to be hashed?

When I call hash(mydataclass) I get a failure on the CatchAll member because it's a dict.

TypeError: unhashable type: 'dict'

Here is my class

@dataclass_json(undefined=Undefined.INCLUDE)
@dataclass(unsafe_hash=True)
class UnknownPacket:
    """Catchall Packet for things we don't know about.

    All of the unknown attributes are stored in the unknown_fields
    """

    unknown_fields: CatchAll

normally I can specify a non hashable like this.

@dataclass_json(undefined=Undefined.INCLUDE)
@dataclass(unsafe_hash=True)
class Foo:

    tPARM: Optional[list[str]] = field(default=None, hash=False)
   ...

the tPARM member won't be used in the hash(foo).

How, if at all, can I declare the CatchAll as hash=false ?
