Can I download packages with vuforia in runtime?

I have a question about the functionality of vuforia and unity, I hope you can help me with this issue, My app is going to have updates I mean, is possible to upload files or packages even if the app is already running or installed?, I figure out that like a control panel in which you can download content directly from a server and running it on my app ( videos, 3D, targets, audios, etc.) Could you help me to know if it is possible? Thanks in advance.

yes, you can use asset bundles for that (but they need to be generated in unity editor) Unity - Manual: AssetBundles

or audio/video/images could downloaded/player directly from web also.

cannot include scripts in the assetbundles for ios and some other platforms,
