Hass.io stops my media server of shutting down

I’m using a Win10 media server, which sleeps most time of the day. Only when a media client sends an WOL to the server it wakes up. Since I’m using Hassio the server doesn’t go to sleep anymore if idle.
Is there anything I could do, to stop Hassio sending any packages that keeps my server awake?
There is no device configuration on the Hassio for the server. The only thing, that I can think of is the device tracker which is monitoring my router home-assistant.io|integrations|fritz, but in the known devices I’ve set the server to be not tracked.
Any suggestions?
