Change brightness of RasPi-7-inch-Display

I am new to RockPi4. Is there a way to change brightness of the display oder to switch it of by software running with Debian?


If there is no software solution, is it possible to disconnect display from power and connect again if needed?

Use I2c-tools…
i2cset -f -y 1 0x45 0x86 0x[00 to FF]
