this is custom rom, so that there is not any android official api to change the feature.

serveral hours later, I got the solution :

1. run adb shell settings list system, get all setting keys and values;

2. change 'Enable true hibernation', and run the same command, compare values;

3. get the feature key is 'systemsleep_open';

4. then run code in app activity

   try {
       Runtime.getRuntime().exec("settings put system systemsleep_open 1")
   } catch (e: Exception) {
       e.printStackTrace()
   }
