FTP Backup storage mount questions

Hello, i am trying to implement a backup task on a dedicated server and need to mount OVH FTP backup storage.
As i see in OVH Manager there are 3 options to access ftp backup: CIFS, FTP, NFS.
So far i was able to mount it as FTP with curlftpfs and implement SSL, however curlftpfs does not support setting mtime to files and directories and i need this functionality.

CIFS mount supports it, however i can't make it use encyrption with -o seal
seal option is supported in SMB3 and above but OVH FTP backup storage server offers only SMB1.

NFS does not support encryption at all.

Is there a way to mount OVH ftp backup storage in a secure way that supports mtime on files and directories ?
