OpenSSH has ChrootDirectory directive for this.
https://man.openbsd.org/sshd_config#ChrootDirectory

And it seems to be supported on Win32-OpenSSH too:

Hello all,
I am in the process of setting up sftp using the winscp guide at this link https://winscp.net/eng/docs/guide_windows_openssh_server.

I have followed the directions, used puttygen to make a private key and I am able to successfully connect to my server using winscp and the key file. My question is, am I able to lock this down so I don't have my users navigating in directories where they shouldn't go in the OS? I would like them locked down to a specific directory and not able to get anywhere else. Is this done through windows permissions, or are there other methods? Using FTPS on IIS, I am able to lock the users down to a specific directory and they can't navigate elsewhere. I am not sure how this works on openSSH. Any help is appreciated.

Thank you,
