Yes, and I've seen ones that have drivers like normal wifi, that come with a python script and one of the lines is for changing the region but I think underneath, it also uses AT commands. And it's certified to use in US, Taiwan and Japan but nowhere else. It's barely documented except as comments in the script. In both of these cases, it's way more prone to being set to the wrong region than a normal wifi router and there is also a big incentive (increased datarate) to just use the US region.
