How to turn off collision for a dodge animation

[ArtB]

Hello I am working on a simple dodge animation for a custom creature, but want to turn off collision while it plays, because melee attacks have really long range and hit anyway. Is there a way to do this?

 

I looked for a text key that does it but did not find any.
