Do you want disconnected sea regions from their sea neighbours or also from their land neighbours?

Well I'm thinking that disconnecting won't help. Instead I may simply remove ships and shipbuilders. The problem with disconnecting sea zones is that agents will then be unable to move between ports.

Turning all of the sea to dead zone (i.e. pink colour) and removing seas from the startpos would take a long time, but could be used sea colours to add more land regions?

No, I won't be doing that. Unfortunately the disused sea regions cannot be combined and used as land regions.
