Silent Deployment without internet access

We work for an organisation which has no internet to the desktop. The desktop cannot have any internet or external access.
We have cubase licensed dongles. We did use version 8 but we now want to use version 11.
Are we able to use version 11 without internet access and can we fully silently deploy it. This includes the library manager which I can’t seem to silently install.

Someone might give you an answer here, but I would suggest you contact the company directly for this advanced type of IT question.
