On my system the disk sleeps and never wakes up on its own only after I set a sleep time manually via terminal command with root user:
hdparm -S 60 /dev/sd{X}
I've tested different time values and came to the conclusion that disk can only sleep when a time is no more than 5 minutes. If its greater than that - the disk would never enter the hibernation state.
You also can force it to hibernate immediately using command:
hdparm -y /dev/sd{X}
apart from that I've only set "Hibernation" option in "Control Panel" -> "Hardware & Power" -> "HDD Hibernation" to 10 minutes and also ran script from https://github.com/AlexFromChaos/synology_hibernation_fixer

Please provide more info, do you run docker in LXC container? can you share your LXC config?
I use Docker in several LXCs, but don't have a /dev/kvm device, does it need to be passed through from the proxmox host?
