Since this is a jam about experimenting and pushing boundaries, the answer is yes. I'd expect that your piece shows some engagement with the visual novels as a format and some form of reading element (for instance, one could argue that an opera with subtitles is a visual novel set to auto), but you're pretty much free to do as you please.
Also, learning a visual novel system like renpy is pretty easy! I do encourage you to play around with it, it's not as intimidating as it might seem. Here's a post (and tutorial) that might inspire you a bit if you choose this route.
