RenPy and Python are the programming languages. I don't know either so I don't know.
If it isn't possible, you could have player choices that lead to different paths, and use that as a means to simulate the effect.
On the reddit sub page is also a link to the DDMC discord. They can be ornery at times, but you can live chat with people who make / made mods and know the programming. I'd look for a guy named Tormuse either on reddit or on Discord.
Good luck!
