Hi,
I feel that the answer is NO!
I explain: You can schedule by software a shutdown on a specific time. You can configure your BIOS to boot at specific time. But, you need to create a software that changes your bios values to set the new boot time. This is a hard work!
Workaround: Configure your XPEnology to Wake-On-Lan, and use your router (with OpenWRT or another custom distribution) to wakeup your XPEnology at specific time.
