How to do back-face culling in an open3D scene with OffscreenRenderer?

Question

I have a mesh and a material that I render with the open3D OffscreenRenderer. The object is one side of a sphere that I have reconstructed. I want the triangles of the mesh to not be rendered, when the camera is looking from the "wrong" direction. This is also known as "back-face culling". I can't figure this out.

Here's the code I'm currently using to get the render:

import open3d as o3d
import numpy as np

def get_render(WIDTH_RENDER, HEIGHT_RENDER, mesh, material):
    render = o3d.visualization.rendering.OffscreenRenderer(WIDTH_RENDER, HEIGHT_RENDER)
    render.scene.set_background(np.float32((0,0,0,0)))
    render.scene.set_lighting(render.scene.LightingProfile.NO_SHADOWS, (0, 0, 0))
    K = calculate_K()
    render.scene.add_geometry("terrain",mesh,material)
    render.scene.camera.set_projection(K,0.1,10000.,WIDTH_RENDER,HEIGHT_RENDER)
    return render

I know that there is a parameter in the open3D visualization class method draw_geometries called "mesh_show_back_face" that does exactly what I need, but I have not been successful in implementing it to the OffscreenRenderer.

I'm not using the o3d.visualization.draw_geometries(), because it is blocking and I don't have precise control over the cameras intrinsic and extrinsic parameters.

Any opinions and recommendations would be very welcome.
