Change basemap before map rendered? about dc.leaflet.js

Some years later but maybe can others too.
You can use .tiles method like this :

.tiles(function(map){
            L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token={accessToken}', {
                attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors, <a href="https://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>, Imagery © <a href="https://www.mapbox.com/">Mapbox</a>',
                maxZoom: 18,
                id: 'mapbox.streets',
                accessToken: '<AccessToken>'
            }).addTo(map);
        })
