Hi maph
Not sure I follow 100% what you mean. Are you wanting VNC to be available as a deployment? If so, there is thankfully a deployment package that will deploy VNC:-

Then if you have VNC Viewer installed on your own PC, you should be able to directly connect.
But if you're wanting to quickly connect to a PC without having to pre-set up VNC; then while you're in an asset page, towards the bottom left is an option for "Remote control" this will deploy VNC quickly to a target, allow you access, then remove VNC after you close the connection.
IF it's neither of these things, please let us know and we'll try to help.
Best
Mat
