Not for SVG, no.

Does the original .svg contain a bitmap, then there is no way for us to
vectorize that. You could split it into rects or run some pixel ->
vector path algorithm on it, but the result wouldn't neccesarily be any
good ;)
I also see from the code that the svg generator doesn't support the
pattern brushes, perspective transforms, conical gradients or
composition modes, so if the original svg is using those, the operations
using these features will be written to the svg as an image. So if you
are using any of the above listed features, then could avoid an image
being generated in these cases.
best regards,
