Help pls, help me, pls pls pls pls pls pls pls

Here is something that someone just told me:

Custom tag "warden_ignores" and code to that alters the warden's behavior so that it wont attack or be triggered by sounds made from entities with that tag. I do not know how else this would be done as Warden's behavior is specific to sound and not entities.

So, how would I just do this?
