How to draw a curved route using SAP UI5 Geo Map control which is not a flight route

How to draw a curved line in GeoMap Control which is not a flight route by not including a map provider's JS API.

I see the control only provides Straight/Geodesic.

I tried using Google Map JS API and am able to draw a custom curved line between two points.

But I am curious to see if it is possible with SAP UI5's Geo Map Control.

Any suggestions/workarounds ?
