Yes, that’s possible.
I don’t know what your setup is, but usually you can use these settings with your favourite client:

Protocol: choose SFTP
Server: your full domain name or IP
user name: your sudo username (use “root” if you didn’t create a new user yet)
Port: default port is 22 (except you changed that manually)
Fill in your password and you should be good to go.

P.S.: allow me to note that it’s pretty strange that you request solutions for your “tech guys”. that’s their job isn’t it?
