How to turn off the screen without stopping calculations on Linux Mint?

I have a distribution Linux Mint 20 Ulyana I wanted to keep my calculations (which last several hours, even several days) running while turning off the screen without stopping my PC. In other words, is it possible to turn off only the screen, like during a logout, while allowing the calculations to continue? Thus, only I, with my password, would be able to access the session. I tried screen, with **screen -n** command line but I am looking for another automatic solution if it is possible?
