Is your feature request related to a problem? Please describe.
I have an Android device connected to a PC and i've developed a system with proxy sockets that sends the data received from the device (scrcpy_server) to the other PC. The problem is that the client wants a device connected via ADB otherwise the client doesn't open. For testing now i've connected a device to the remote PC but i use the already implemented --tunnel-host and --tunnel-port to use my solution and the client opens with the video stream and all works.

Describe the solution you'd like
I'd like an option --no-adb on the client that tells to the client to not use ADB and to create the sockets by the tunnel that i define with the --tunnel-host and --tunnel-port options

Describe alternatives you've considered
