Looks like that applies to all 13" models as well. Their knowledge base does not list a BIOS update for this model yet, but there is a post about it on their forum, and the Linux instructions for that are the same as that of the other Framework models.
I don’t know about the 13, but on the 16 you can update via USB, no OS required. Kind of annoying, but it works.
