@hmof which OS are you using? I'm using OMV and had to set these settings the OMV way, but at the end the source of truth is always etc/default/cpufrequtils
 
	 
 
	If you are using OMV you have to use env variables to set the values and then deploy. In the end OMV use ENABLE=true, even if it is deprecated for armbian.
 
	 
 
	Hope this helps.
