How to remove the glint from Debug stick (1.14 Java)

No, you can't remove the enchantment from the debug stick without removing the enchantment texture from the game (glint.png). The debug stick will always remain enchanted; without mods this won't be something you can change.

If I remember correctly, you can use any tool with some janky attributes like an unbreakable carrot on a stick with 28 damage. This results in an item thats not obtainable in survival and pretty easy to check for, since you can check for an item of the type carrot on a stick with 28 damage and the unbreakable tag.

For creating such tools, you could use a website like this

This also allows you to change the texture of every item you add this way, which is generated by the website as well

EDIT:

I forgot to mention that these tools do not have the glowing echanted effect, since they're unbreakable via the tag and not via an enchantement
