how can I change default accounting (radacct table) update time?

Hi, I am using Simultaneous-Use := 1 . When I disconnect wifi or in a power loss, I am facing an issue that I can't connect to the server again. I saw that after 5/6 minutes later, I can connect again that means " acctstoptime" is not null then. so I guess after 5/6 minutes later freeradius server check if the user is ideal then disconnect or send a account-stop request or fill "acctstoptime" field. Now I want to change that 5/6 minutes to seconds or at least 1 minute. How can I archive that? I used Acct-Interim-Interval which keep updating even after the user is not connected on a power loss. Thanks
