@Anonymous Welcome to Microsoft Q&A forum and thanks for reaching out here.
As per my understanding, you are looking to upload a file to Sharepoint using Synpase data pipelines. Please correct me if my understanding is not accurate.

Hence you will have to work around by creating a custom code and executing it in Synapse pipelines custom activity or you can implement a solution which utilizes logic app
