Is there a way to force the mouse cursor to move itself?

Hello,
I have some query / problem.

I have a business computer and my work sometimes also requires night hours and I must be logged in to the system.
Unfortunately, the IT specialists in our company made the screen on the computer automatically go blank and lock it (you need to enter the password) after 3 minutes of inactivity (no mouse movement or keyboard clicks).
And I have a question .. is it possible to do something to keep the mouse cursor moving all the time? Any tricks?
I have one way - put one mouse on the other so that the laser beams are directed at each other, although it requires practice and it does not always work.

Any ideas please

Maybe something like this: https://www.murgee.com/auto-mouse-mover/

I forgot to add that there is no program in the game because I do not have the right to install anything ..

Maybe some reflective pads? I really have no idea: /

Or if you have more time and skills, for example: https://www.youtube.com/watch?v=CN99N9l1V7I

You don't need to install anything http://www.zhornsoftware.co.uk/caffeine/index.html#download this program requires no installation and does exactly what you want it to do.
