At the moment there is only one general tick in mutable to either activate or deactivate cloth. This affects all pieces of cloth in the mutable graph and can’t be turned on or off individually.
Is there a way to turn some of them on and others off?
Unfortunately, not today. The way it works is explicitly that if there is an attached clothing asset on a mesh and you have EnableClothing turned on, it will grab that meshes clothing data and apply it. I’ll raise this up with the dev team as a feature request, but if you wanted to explore creating your own approach to bypass it you could start looking at UCustomizableInstancePrivate::BuildOrCopyClothingData and coming up with a scheme to decide if you want to include that data or not.
