With the following event handler in a scenario, or entered in game on the command line:

script.on_event(defines.events.on_chunk_generated, function(event)
  local surface = event.surface
  if surface.name == "nauvis" then
    local mgs = surface.map_gen_settings
    mgs.seed = mgs.seed+1
    surface.map_gen_settings = mgs
  end
end)

Thanks for the report however in this case you simply can't do that.

Changing map_gen_settings requires all chunks being generated are finished immediately which fires the chunk_generated event which recursively repeats.
