How to disable automatic push install

Backup Exec 2014. Noticed there are lots of log-files in C:\ProgramData\Symantec\Backup Exec\PushLogs directory. Currently I really don't want Backup Exec to do automatic push installs (which fail). I am in a process of fixing server environment manually and this complicates things.

Don't find anywhere setting to disable this. Maybe it needs registry change but not sure which one. Maybe:

HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Backup Exec For Windows\Backup Exec\Engine\Agents\Auto Discovery Enabled ?
