Disable filename modification

Is there a way to disable the "Replace" filename modification feature using the .NET assembly?

This feature is available with the user interface https://winscp.net/eng/docs/ui_transfer_custom#other

but I'm not able to find how to disable the replace behaviour with the .NET assembly API.

Use ReplaceInvalidChars raw configuration option.

Thanks, this is exactly what I was looking for.
