sftp download files with a sudo user

Hi - I am downloading file(s) using sftp connection using a non-root user which has sudo access. There are certain files which get downloaded, but for few files we get permission denied. The issue seems to be the due to permission on the files.
While searching on internet, it was observed that sftp can be connected as a sudo user which eventually can download the file.
Is there any mechanism to get the SFTP client with elevated access like sudo.
sftp -s "sudo /usr/libexec/openssh/sftp-server" user@hostname:/var/log/filebeat/filebeat .

One alternative approach could be to copy files locally and then download the same, but this duplicates the work. For example
- cp /var/log/filebeat/filebeat ~/filebeat
- sftp user@hostname:~/filebeat .
