ZSU-23-4 which is intended to shred armor at a couple of km
--
The ZSU was designed for AA not anti-armour, and most if not all modern IFVs are supposed to resist rounds that small.
The AA units with good anti-armour capabilities are probably 30 to 35 mm, with dual feed to allow switching to APDS rounds, and that is only good against APCs and IFVs, not MBTs, or probably, heavy IFVs.
