Edit 2: My bad, I assumed power nap == "wake for network access". This no longer seems to be an option in macOS 26.
Mine's set to "Only on Power Adapter", which makes sense.
Edit: On an M4 MacBook Air running macOS 26 DB
It's not the macOS 26, its the option is not available on Apple Silicon machines. I think it is always enabled.

Turn Power Nap on or off for a Mac desktop computer On your Mac, choose Apple menu > System Settings, then click Energy in the sidebar. (You may need to scroll down.) Turn on Enable Power Nap. Note: This option is only available on Intel-based Mac computers.
You can see (and change) the settings via Terminal, 'pmset -g' will show the current options.
On Apple Silicon it's not available under the battery settings, but you can still set it.
> sudo pmset -a powernap 1
-a is an option to set it for battery and plugged-in. If you want only either you can do -b for battery, -c for charger
You can also check the settings with:
> pmset -g
you can also use pmset to programmatically enable/disable low power mode (which i do when the battery gets too hot for my liking even before thermal throttling kicks in)
