Controller mods were also suggested, but they're rarely updated and often only work with specific Minecraft versions so sticking with Steam Input and just adjusting a few keys is the best choice for that. Some YouTube comments suggested trying out some optimized modpacks, but really I didn't see a big enough difference in terms of performance or power use to make them actually worth it on Deck compared with vanilla Minecraft when testing on the same map seed.
