REST API - How to delete first section of a document ?

Everything is in the title, I want to replace a batch of documents in a FileCabinet. I cannot use a checkout/checkin process as versionning isn't enabled on this file cabinet. So I want to attach the new document to the existing record and delete the first document (section).
Is it possible ?

You can delete a section via REST-API by sending a request to the endpoint within the platform using the DELETE method. You can use following REST call to delete a section:

[DELETE] https://{URI}/DocuWare/Platform/FileCabinets/{FCID}/Sections/{SectionID}
