More external video output or a kind of solution

as maybe someone noticed, my need is about desktop using, but i want a fully libre system, with a good specs, so purism is the only choice at the moment, but there is only laptops no news or info about desktop, so even if i dont like the idea i’m considering to use the laptop as desktop replacement
i see there is only one video output, but i need to use 2 external monitors, so there is any chance to have one more output in the future, if not there is any trick could i use for use these 2 monitors with one output only?
