Keyboard Backlight

Hi,
I’m running Linux Mint 20.2 Cinnamon on a laptop I got from Think Penguin. . . Is there a way to turn on/off the keyboard backlight?
Thanks!

On mine, i hold down the fn key then hit f3 to dim the keyboard, f4 to brighten it. But I do not have the same keyboard tho. Same process for the display brightness f5 to darken, f6 to brighten it.
