Best Way to Modify Vanilla Achievements?

[crude temple]

Im currently working on a project that has a survival world and a creative mode lobby. I want to modify all base achievements in the game to only activate when the player is in the survival world because getting them in creative mode would be trivial. I have two main questions:

-is there a resource or place where I can easily get the vanilla advancements (version 26.1.2)
-are there any modifications that would be easy to apply to most if not all achievements that could suit these purposes (example: achievement is only granted to players with a specified tag or team?)

For getting the vanilla assets you can go to: https://github.com/InventivetalentDev/minecraft-assets/tree/1.21.8/assets

They're also all just in the vanilla data pack, which you can access by opening your version's jar file in your .Minecraft folder with an archive program like 7zip or winrar

For generating an advancement you can go to: https://misode.github.io/advancement/ you can add any additional conditions there
