Customized default zoom level in mapbox visual in Power BI

Hi Expert, 

I'm using mpabox visual in show circle in dashboard.  Lat & Long for each data point was provided with all data location was within APAC.

When filters (country) was chosing, it zoom in to specific country, which is fine, but when user de-select filter, it zoom out to somewhere around Malaysia (left photo in below) instead of zooming out further to show entire APAC map (right photo in below)

I've web surf online with one of the post claim it's the data problem where mapbox will calculate the center point of all available lat long but seems there's no solution on this.  kindly ask is there ways to customize default zoom level when zooming out (no filter select status) ? Or can I create map with default zoom level in mapbox studio and use in Power BI ? Or is there other workaround ?

Thanks a lot.
