Using PowerBI for integrating to .NET application on-premise

We are developing a .NET application that we are already reselling that specifically integrates to a desktop application. This is an on-premise desktop application using PostgreSQL.

We want to build a dashboard in our .NET application and trying to figure out how to do that with Power BI desktop without having to publish them to the cloud Power BI. Is there a way to publish the dashboard to our .NET app so that the data presented in the dashboard will be from the on-premise database without publishing them to the cloud Power BI? We don't want to use the cloud Power BI option.

I hope this makes sense. I did a search on here and could not find a specific answer to my questions
