Topography on Folium?

I wonder if it is possible to display topographic lines with the python library Folium.
If I have a topographic map on QGIS, is it possible to transform in to a format that would be possible to display as a layer on Folium?
What are the general steps to create that?

Thanks

This doesn’t seem like an OpenStreetMap question?

There might be someone here who is familiar with that software, but you might be better off on a more generic GIS Q&A site.
