Custom item function details

So I have a custom item that has the food and consumable components so that I can use an advancement to detect when it's used. A couple things I was wondering.

Is there a way to interrupt the animation? I like it but kinda want it to end after a second or so.
Is there a way to stop the player being slowed while using it?
Can you make it unconsumable or is best practice just to set the consume seconds super high?
