Now we create data source like this

var dataSourceBuilder = new NpgsqlDataSourceBuilder(dbSettings.Value.ConnectionString);
dataSourceBuilder.BuildMultiHost();

It seems that this implementation implies a static connection string, but in our scenario we have our own ConfigurationProvider where we periodically update the list of hosts, for example, the database stopped coping with the load and additional replicas were added to it, it mean that we need to restart service. We need something like UsePeriodicPasswordProvider, ability update connection strings periodically

Is there any way to do what we want now?
