I've not seen any 64GB SODIMMS yet, which is likely why. When they to turn up, then you should be good as the spec sheet from AMD states 256GB.
The 24/48GB ones are not officially supported according to the Framework knowledge base. AMD haven't validated them. They're a new concept where the capacity isn't a power of two number so it's uncharted territory.
