Serviio no hdd idle / standby on the same hdd

Hello is it possible with serviio what is installed on the same hdd to go into standby - idle? If so how? My system is linux debian 10. the hdd has previously gone into idle. I have turn off auto refresh database. I have loaded the serviio folder in ram no success. I have done plugin disable in serviio.sh this unfortunately did not help either. Thanks a lot!!!
