Hi Albabes,
This image you shared is the typography system: https://snipboard.io/DB13Wi.jpg
It’s in Appearance > Customize > Typography.
It’s not a module that can be activated/deactivated in Appearance > GeneratePress. It’s activated by default.
Moreover, in Appearance > GeneratePress, under the “Start Customizing” section, there should be a Typography Systems item with button “open options”. You can access the Typography system from there as well.
Hope this clarifies!
