The answer of the following question may be well-known in the field of Geometric Topology, so I ask for help in here.

Does the total space of circle bundle over a closed hyperbolic surface admit a Riemannian metric with non-positive sectional curvature?

In particular, the circle bundle which comes from the tangent bundle of the hyperbolic surface is directly related to my thesis about positive scalar curvature.

Since if it does not carry metrics with non-positive sectional curvature, it may not be an enlargeable manifold, which is an obstruction of admitting positive scalar curvature metrics.
