Select the object (ICBA_BR...) not the modifier to enable the ability to add a visibility track.

Note that some renderers, e.g., Arnold, do not support the visibility track. In that case use a cutout map that transitions from black through gray to white to effect visibility.

Another option, depending on your requirements, is to use a ProBoolean subtract as done here.

Thanks for your answer. But when I tried to add visibility track on ICBA_BR... its all visible -or not- all object. I want to add visibility track only slice modifier. Is this possible?

How about keyframing the position of the slice such that it doesn't slice the object when you don't want a slice? Use a step function for these transitions.

Thanks I can use this. But Slice modifier's plane uses high performance. I have performance issues with this solution.

You could always have a clone of your object that does not have a Slice modifier, and animate that version to become visible when the other becomes invisible. So it appears that the Slice has disappeared, when in fact the object with the slice has disappeared and an unsliced version has appeared in its place.
