I've found a page on the Framework website which states the laptop can drive 4 displays simultaneously, but is it possible or advisable to do this from a single USB-C port?

Framework 13 AMD

Intel supports routing all the available display pipelines through a single DP MST connection (any DP output). While AMD does not themselves publicly document this, they do support the same, just as Nvidia does.

Depending on involved peripherals, you might run into bandwidth limits. 4x 4K60 for example is possible over a single DP connection and Lenovo for example even lists that as supported with the right dock for their AMD laptops.
