Turn screen off on Pirate Audio: Headphone Amp for Raspberry Pi

Hello,

On the “Pirate Audio: Headphone Amp for Raspberry Pi”, is it possible to turn the screen off completely (e.g., to save power, or to completely stop any light emission)?

Thanks!

This command turns off the backlight:

disp.set_backlight(0)

assuming that

import ST7789
disp = ST7789.ST7789(...)
