Not that I'm aware of. I think you'd best be served by using a regex
to parse the particular input string you want and extract the zone,
easting and northing, and then setup a QgsCoordinateTransform to
convert from the detected UTM zone to WGS84. Should be ~5-10 lines of
code to do, without needing any additional Python libraries.
