systemd-logind - Watching system buttons on /dev/input/event0

Hi, I may not have noticed this before, but now whenever I log in via SSH I see this message in the journal:

May 06 19:12:54 router systemd-logind[384]: Watching system buttons on /dev/input/event0 (Power Button)
May 06 19:12:54 router systemd-logind[384]: Watching system buttons on /dev/input/event2 (HID 0557:2419)

Is there any way I can turn it off? It's not a laptop etc - I never want to use sleep and hibernation there.

I looked at what all systemd-logind does:
