I have had good experience preventing this from happening by disabling Wake-On-LAN, or enabling deeper sleep modes that remove that capability, on my systems that don’t need it.
My suspicion is that many devices these days are pinging the LAN devices around them, for instance other Windows machines looking for printers and network shares, and this is waking devices that are in higher sleep states.
