Not that I'm aware of. You could try using IfcConvert for exported IFC files:

https://docs.ifcopenshell.org/ifcconvert.html

If you have access to Rhino, use it as an intermediary step to clean up geometry then export as STEP.

(For the most convenience you should use an IFC supporting add-on like GeometryGym or VisualARQ/Lands Design).
