What is the problem? How to switch Pi Camera ON and OFF

**What did you already try to solve it?**Everything I know

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)I have a Raspberry Pi3 with a Raspberry camera V2 running Octoprint as OS
I can see the video image from the camera on octoprint on my laptop under the control tab.
I have putty running on the laptop and can see the terminal window and input info and commands.
I have VNC running on Pi3 and laptop and can interact with the Pi3.

I want to be able to switch the camera on and off. What are the commands and on what system
