Secure folder backup on Note8

[Leosam]

Is there an authentic way of backing up my Note8 Secure Folder contents onto my laptop (using a USB cable) or external USB drive without having to resort to 3rd party apps/services? As far as I can see, currently the *only* way of doing this is by backing up the Secure Folder onto Google Drive, which I think is unacceptable. I don't trust cloud services, sorry.
