I don't understand what you're asking I'm afraid. The script and agent switch options are all that come with DCS:SA, it doesn't have any push deployment functionality in it like SEP does.
This means you must look outside of DCS:SA to GPO, Altiris, LANDesk, SCCM and the like. In which case, your deployment schedule, and how long it takes to accomplish it is determine by that solution, not by DCS:SA.
It's even possible to use PSExec to push the agent out for free if you wanted to, but it's not something I'd usually recommend, and it is still outside the bounds of DCS:SA's functionality.
The tools you've mentioned can all get the agent deployment done, what specifically are you after? For example, once setup in Altiris, it's possible to send "tickle" packets to Altiris agents to tell them to perform an immediate install, but that is Altiris functionality and not DCS:SA.
