How to disable a specific stat or stat level of an enchanted book

[abm991]

Here's my config file:
{
// -----------------------------------------------------------
// Item Obliterator by ElocinDev
// -----------------------------------------------------------
//
// How to add items?
// - They are json strings, so you need to separate each
// entry with a comma, except the last
// - If you start an entry with !, it will be treated as a regular expression
// Example: "!minecraft:.*_sword" to disable all swords
//
// -----------------------------------------------------------
// Do not touch this
"configVersion": 2,
// -----------------------------------------------------------
// Items here will be unusable completely
// Example: minecraft:diamond
"blacklisted_items": [
"examplemod:example_item",
"fwaystones:void_totem",
"biomemakeover:enchanted_totem"
],
// -----------------------------------------------------------
// Removes an item if it contains certain nbt tag. If the whole entry (or expression) is present, the item gets removed.
// Use with caution! This is a very expensive operation and can cause lag if you have a lot of items blacklisted.
//
// Example to disable a regeneration potion: Potion:"minecraft:regeneration"
//
// You can also use regular expressions by starting the value with !
"blacklisted_nbt": ["enchanted book"minecraft:death_trade""],
// -----------------------------------------------------------
// Items here will not be able to be right-clicked (Interact)
// Example: minecraft:apple
"only_disable_interactions": [
"examplemod:example_item"
],
// -----------------------------------------------------------
// Items here will not be able to be used to attack
// Example: minecraft:diamond_sword
"only_disable_attacks": [
"examplemod:example_item"
],
// -----------------------------------------------------------
// Items here will get their recipes disabled
// Keep in mind this already is applied to blacklisted items
"only_disable_recipes": [
"examplemod:example_item"
],
// -----------------------------------------------------------
// If true, the mod will use a hashset to handle the blacklisted items
// This is a more optimized approach only if you have a lot of items blacklisted (20 or more is recommended)
// If you just have a small amount of items blacklisted, keep this false
//
// [!] Enabling this will disable all regular expressions
// [!] Does not apply to NBT, only item blacklist / interaction / attack
"use_hashmap_optimizations": false
}

Use the /data command to see how certain nbt applies, then add that nbt to the blacklist
