autodesk forge – Conversion from IFC to SVF

To convert from IFC file to SVF output for Autodesk viewer, derivative webhooks (forge.autodesk.com/en/docs/webhooks/v1/developers_guide/overview/) can be used.
Is there another way to do the same thing like using “autodesk design automation” and if yes, which option should be chosen?

For conversion from IFC to SVF using output-advanced-conversionMethod-v3 instead of conversion method legacy or modern, which library for .NET can be used, because in Autodesk.Forge you can´t select “v3” option, only legacy or modern.

For “autodesk design automation” what king of activities can be used with the same functionality than derivative API?
