It's unlikely any complex narratives could be encoded there, though.
Possibly a bit like the e.g. the Mycenaean Linear B script. Which is fully decoded and well understood. But despite having a full fledged writing system they mainly used it for accounting and such. They can tell us about how many goats, sheep and various good they had they had but don't tell as much about the society or history as such.
Heculaneum manuscripts are kind of the opposite from the Quipu in the sense that we have zero issues understanding the actual text/symbols just extracting them from the destroyed scrolls is rather complicated.
Minoan tablets are maybe a bit closer and little progress has been made there (then again we are fully capable of reading the script just have no clue about the language it was written in).
