Disable Endurance .filepart in batch script

How can I disable endurance via a script? The file upload is used in a batch file and the unwanted functionality uploads files by adding a '.filepart' extension to the file and then changes the name to the original file name when the upload completes? This needs to be disabled. The GUI is not being used by the way, only command line. For example the below parameters have been tried to disable this feature without success.

open sftp://user:pass@ftp.com:100022 ResumeSupport=2
open sftp://user:pass@ftp.com:100022 ResumeSupport=2 Endurance=Disable

Use -resumesupport switch of put command:
