You can enumerate all views, if you find a 3D View you can just select it into ActiveView. If you don't find one, you may have to create a new 3D View.

E.g. something like:

View3D view3d;

using (var collector = FilteredElementCollector(document))
{
    view3d = collector
                    .OfClass(typeof(View3D))
                    .Cast<View3D>()
                    .FirstOrDefault();
    // Note: may want an intelligent predicate in the call to FirstOrDefault() depending on your needs
}

if (view3d == null)
{
    // Need to create the view
    // I don't think you will need this, since there is almost always a default 3d view, but if you do look for View3D.CreateIsometric API call
}

// Activate the 3d view
uiDocument.ActiveView = view3d;
