Remote desktop with locked local screen

I'd like the ability to remotely connect to my desktop while keeping it locked locally (somehow) -- perhaps similar to how Remote Desktop works on Windows. (Last time I tried doing that via Vino-server, it just showed me the same lockscreen over VNC...)

This would be a great privacy feature, because sometimes I want to connect to my work PC without e.g. coworkers or cleaners seeing everything I do on the physical screen. (Assume that the physical screen cannot be turned off or is trivial to turn on.)

(RDP pretty much detaches the entire display from local GPU and attaches to a virtual dummy GPU. I have no idea how it'd be implemented here; I assume it would need Wayland at minimum.)
