I know there is a configuration somewhere to allow me to edit feature classes in an sde database which is a data source for Feature Services. At the moment I cannot edit any of the feature classes in my dataset because a list of "Locks" are shown when starting the editing. But a few years ago when I set up my other SDE Databases, I was able to overide this resistriction.
I have ArcGIS Server 10.5 on Windows Server 2012 and Desktop 10.7 on Windows 10.
Would anyone know what I have to do?

You likely have people editing with the same database permissions, a higher level could boot the schema locks. You may have to look into your user role structure or versioning, as this will become a pain.
