Have tried rc.local command and grub config kernel parameter with no luck. Think KVM settings override those of mine.

What commands have you added to /etc/rc.local? Unfortunately droplets do not use grub so editing its config file won’t have any effect.

The best choice is sysfsutils. See this answer.
