For an unattended SCCM console deployment you have to run  Setup.exe using the /script and the /nouserinput command line option.

For example, to perform an unattended installation with no user input, the command line would be:
“\\SMSSERVER\SMSSETUP\BIN\I386_\Setup.exe /script\\SMSSERVER\SMSSETUP\Adminui.ini /nouserinput”
The adminui.ini would be:

[Identification]
Action=InstallAdminUI
[Options]
SiteCode=3 letter Code of your SCCM server
SMSInstallDir=C:\SCCMConsole
ParentSiteServer=Name of the SCCM Server
SDKServer=Name of the SCCM Server
