Possible to Disable Screensaver? What I'd like to achieve

On my Macbook Pro with latest macOS - every X minutes, the screensaver turns on for X seconds, then the screensaver turns off. This application by defaults runs every time the MBP turns on, with the option to disable.

Question

I've started to create this using Automator but I'm stuck at disabling/turning off the screen saver. Is it possible to do this through Automator or is there another way to achieve this?
For MacOS 10.15.4 Catalina, you can start a screen saver after 15 minutes and then stop after 15 seconds you can use the following Automator Application.  



You then need it to launch at login, by going into System Preferences>User and Groups>Login Items and add your screen Saver Application.
