Screen sharing but keeping remote screen locked

When I use the Screen Sharing app to connect to remote Mac, it seems that the remote display shows everything I am doing remotely, and if someone else passes by, the remote Mac is completely unlocked and accessible. Is there a way to connect to a remote Mac in such a way that the remote remains apparently locked, so that my remote session is "virtual" ? I think Remote Desktop has this ability (it's called "Curtain", see https://support.apple.com/guide/remote-desktop/control-or-observe-one-client-computer-apd2450a787/mac) . Does Screen Sharing app have something similar?
