If you'd -really- need one, you could always take Biestial hybrid to a kingdom that has the preferred regional affinity that you'd want.
Furthermore, while it's not the same, Regional Adaptation unlocks another region for your faction to pick. While it won't stack, it'll give you more options from different regions.
@Mark Osse You could have a higher leveled class take forbidden lore to the earth sphere of the fey kingdom and pick their Subterranean Movement trait that grants Subterranean Movement 3. Alternatively, you can make a class a shaman and pick the trait for it.
While it's not the same as using tunnels, they'd still be digging : )
It is intensional for the vermin.

Was looking at more tunnels for molemen but I guess stacking tunnels is OP
