I have a 16" MacBook Pro running Catalina 10.15.4 but without the problematic "supplemental update", "Power Nap" is disabled for Battery and Power Adapter, and yet it wakes up every two hours when sleeping, like all through the night and so. Why?

Might be tcpkeepalive, which I believe sends a packet to maintain a server connection every two hours. You can try turning it off:

sudo pmset -a tcpkeepalive 0

If you only want to disable it for battery power:

sudo pmset -b tcpkeepalive 0

Thanks, will try that.
