The Design Studio does not allow users to change the Virtual Dataport Server information(such as host, port, database name) in the login page. But, as you know, it is possible that the user can provide the URI of the Virtual Dataport Server by adding the URI parameter to the URL. I would suggest taking a look at the[ Design Studio Preferences](https://community.denodo.com/docs/html/browse/latest/vdp/administration/starting_virtual_dataport/starting_the_design_studio/design_studio_preferences#:~:text=The%20users%20can%20provide%20the%20URI) section of the Virtual Dataport Administration Tool for more information. Currently, the enhancememt request has been raised for the user to be able to configure the URI of Design Studio and our internal team is working on it.
Hope this helps!
