As Michael Hampton said, this doesn't make sense. The only thing I can think to do is disallow access to those commands with Linux ACLs from the users that log onto your server via SFTP and/or, depending if you're running SFTP in a chroot jail, the specific user that is running SFTP.

You did not specify, what SFTP server are you using. I'm assuming the OpenSSH.
The sftp-server (and the compatible internal-sftp) has the -P and -p switches to black/white list certain SFTP requests.
You can use them to disallow the symlink requests:
Subsystem sftp internal-sftp -P symlink

You can only pass args to the sftp command when using ForceCommand, not Subsystem. If you do what the other answer says, the -P arg will be silently ignored!
The correct way:
Subsystem sftp internal-sftp
ForceCommand internal-sftp -P symlink
