I have tried implementing a custom settings.xml config (provided in Additional information). When I have implemented this config, it results in an infinite reboot loop.
Also, are the logs (dayzps/config/DayZServer_PS4_x64.ADM) persistent, or is it a rolling log that gets reset during every restart? Is there a way to access a log store on the server? I ask because if I have the server set to automatically restart, then I currently can't access logs from before the restart in case I have to resolve an issue that occurred in-game that we would use the logs to verify.
