I installed and configured ProFTPD with SFTP option. But when I'm connecting to the service via WinSCP or native OpenSSH scp client, after I enter the user credentials, I get banner similar to SSH motd.

Linux debian1 4.19.0-12-amd64 #1 SMP Debian 4.19.152-1 (2020-10-18) x86_64

The programs included with the Debian GNU/Linux system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.


Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent
permitted by applicable law.
You have mail.

How can I disable it? I've tried various "Display" options, but unsuccessful.

The SSH authentication banner is configured in ProFTPD using the SFTPDisplayBanner directive. Though this is sent before authentication.

Another source of the banner can be server's PAM module. You can disable forwarding of the banner from PAM to the client using SFTPPAMOptions directive with NoInfoMsgs flag.
