SMB network timeout default setting

I use Kodi on an Android Xiaomi Mi Box to watch content from a NAS. The NAS is set to go to sleep at 10.30. When I open Kodi in the morning to watch something, after I’ve watched something the previous night, it takes 30 seconds to ‘realise’ the NAS isn’t contactable and to time out and allow me to go to the home screen. I’m using the back button to back out to the main menu where I can then use the wake-on-lan add-on. Is there a setting to change this timeout to something lower?
