Using v-mapbox with private (Offline) Mapbox Atlas instance

[LumineLittlelight]

Hi!

We are trying to migrate our app that is using v-mapbox into on-premise Mapbox Atlas server instance without internet access.
Based on mapbox documentation, we need to adjust the base API URL and update the Mapbox GLJS API URL.
https://docs.mapbox.com/atlas/guides/products/

Since now the VMap wrapper only expose certain mapbox gl properties, may I know how do we update these base and Mapbox API URL?

Appreciate your assistance.
Thank you.
