Do you mean:

You can hide the yellow cube (still make it renderable) then use a Mask layer so it masks off the area of the blue cube

Or you can set each material a material index, enable the material index pass and use an ID Mask node to make a mask for that material.

I make my object like that but my project need freestyle, so when I render using freestyle, it’s still draw black line on hide part, what do I do?
