You should be able to create a custom package with restore only:

https://documentation.commvault.com/2022e/expert/2027_creating_custom_package_for_unix_linux_and_macintosh_computers_using_installation_package.html

Once done you can use that for an unattended / silent install.

Not sure if you have tried that or can’t locate the restore only option in the custom page creation step?

I hadn’t been able to update this since I managed to find an option ~

Yes!  do the custom package, as Damian Andre indicated.  You’ll get a tar file - expand it on the client, then:

1. Copy the default.xml to save it
2. vi default.xml
3. find “restoreOnlyAgents” - toward the end of the file (in CVInstallManager_ClientSetup)
4. change that to “True”

I’ll update this to confirm that this WORKED.
