It would probably be much cheaper to buy a Framework without RAM and then install 96GB yourself anyway, even if they did offer a 96GB option. It looks like they charge roughly the same amount for 2x32GB as it costs to buy 2x48GB DDR5 SODIMMs at retail.

There are working 96 GB kits. Check the Framework forum and also reddit.

the CPU in framework 16" will happily run 2x48GB SODIMMs.
