Are the Cylces render passes with antialias ?

Hi guys,
I tried a lot of things, boosting samples, raise the resolution of my render a lot and I understand this: the beauty pass (the combined), the AO and few other are with antialias, GlossDir, GlossInd, DiffDir ecc are without antialias. Is it true ? I can’t find this information. My test is very simple, I created a new scene with a sphere with a principled shader with 0 roughness, no metallic, an hdri or a sky generated by Dynamic sky. Am I right? I need to composite the passes out of blender, how can I obtain a clean pass? Thanks a lot!
