Aura H2O How to disable header and footer?

Hi guys, I am new to this device.

When I watched the youtube Kobo Aura H2O review, they are able to disable the header and footer in the reading setting menu, so more space for reading in the display.

But in my device, I don't have that option. Why? Did I miss something? The software version shown in my device is 3.19.5761.


Thanks.
