How to convert svg to dxf in CLI (Inkscape preferably)?

Hi guys,

in my script I need to convert svg to dxf.

I have good results with Inkscape - save as dxf (it supports polyline) but it is GUI and I would like to do the conversion from a blender add-on.

How to do it in CLI? For Inkscape I found only options for conversion to pdf, ps…

Of course You can also mention other reliable CLI programs (usable in Linux).
