[1.16.5] Vertically generating chunks (or something along those lines)

[ImNotJahan]

So this is probably something very difficult to accomplish, but is there a way to have chunks generate vertically in a certain dimension, as I have a vertical dungeon. Due to chunks only having an x and a y it has to do procedural generation, which I'm not very good at making efficiently, on every floor for every chunk, so it can lag a lot.

Edit: here's the chunk generator incase needed: https://github.com/ImNotJahan/danmachi-mod/blob/master/v1.16.5/src/main/java/imnotjahan/mod/danmachi/world/dimension/chunkgenerators/DungeonChunkGenerator.java
