You are correct.
I have attached the Print screen of the place you are looking for.
You need to go to: Servers->Overview and choose the Endpoint Server.
After you clicked on the endpoint server there is a tab called "Endpoint Settings".
Inside there you can look for "UI.No_Scan" and you will find it, you need to change the value from 0 to 1.
Kind Regards,
