Export DXF to SVG without strokes and extra paths

[speix]

I am exporting a dxf that is hatched to an svg.
Works fine but I cannot get rid of the autogenerated strokes, and the script still creates a C1 class on the final SVG with numerous extra paths that define the strokes of all the included shapes.
Is there a built-in setting to get rid of strokes and those extra paths from being generated?

def export_svg(doc, svg_out):
    ctx = RenderContext(doc)
    backend = svg.SVGBackend()

    cfg = Configuration(
        background_policy=BackgroundPolicy.OFF,
        color_policy=ColorPolicy.MONOCHROME,
        lineweight_policy=LineweightPolicy.RELATIVE_FIXED
    )

    Frontend(ctx, backend, config=cfg).draw_layout(doc.modelspace())
    page = svg.layout.Page(0, 0, svg.layout.Units.mm)

    settings = svg.layout.Settings(
        scale=1,
        fit_page=True,
        max_stroke_width=0.0,
        min_stroke_width=0.0,
        fixed_stroke_width=0.0
    )

    svg_str = backend.get_string(page, settings=settings)

    with open(svg_out, "wt", encoding="utf-8") as fp:
        fp.write(svg_str)
