I am trying to keep the Rock64 I have running on Armbian 10 Buster Version running Home Assistant in a Docker container running 24 hrs a day 7 days a week. It seems like it the OS goes into s sleep mode or power savings mode and I can not keep it up running 24 hrs a day. When it is up and running works very good but is there any settings in the OS that I can access from terminal (no running any gui or desktop) that I can invoke to keep it up and on line all the time?

I have a Rock64 running the armbian buster 10 OS, and then Running Home Assistant in a Docker. The problem i have is after a period of time the OS puts the Rock64 to sleep or uses power reduction and that drops the Home Assistant , and SSH. This is do not want t happen sice i want the OS running full time and all the time to monitor the Home Assistant and sensors. How do I stop it from going to sleep or into power reduction and have it always available?
