Where are my Matchlock Monks?

[Rothe]

I can see from the encyclopedia that there is a monk matchlock unit, but I can't build one.
Is it actually possible to train these guys in the vanilla game?
If not, is there perhaps a mod to allow them in?

Matchlock Monks are in this mod

Like Naginata cavalry, they are in the game but they're not available for human player without changing some files
