I can't yet see the picture as it is still awaiting approval but I'm working on the assumption that it's a white wall box with one or more F type connector sockets on it.
That being the case, then the answer to your question is yes ... but...
The white box should have a coax cable leading out through the wall into the brown omnibox on the outside. In there the cable should connect back to another coax cable which vanishes underground and leads back to the street cabinet. So in theory you just need to get the self install package, connect the Hub to the white box using the supplied cable, call up to activate it and be good to go.
You could check the connections in the omnibox all look ok but you can't tell if it's all connected up in the street cabinet - VM might not necessarily know if the cable has been left connected for the previous occupants or if an engineer had disconnected it at some point.
The concern is that you might order a self install, it doesn't work, you call for an engineer to come out and only then find there is a broken cable somewhere. Meanwhile you are paying for a service you can't get and playing 'whose fault is it' ping-pong with customer services.
OK to be fair, that's a worse case scenario, I'd call VM, see what they have to say and give it a go personally.
