In Minecraft there are commands for op enchantments, for example for sharpness 100 or so, but there's a limit, e.g. Sharpness 10000000000000 is no longer possible. But can you avoid this by some trick or so that you can enchant more?
Plugins / modifications
Otherwise it doesn't work?
No, because the Vanilla version is provided by Mojang with the values you specified.
So I can't change anything in the config or something?
No. Only with modifications / plugins for servers
