Tabview buttons initialization event


I debute with UI in generally, and i use LVGL that i find very good Library,
i’m using Tabview in tabview to constitute a menu bar in bottom of screen, and i want to change the shape of buttons (for example : add a vertical line between buttons) ,
and i noticed that the first button is activate (checked) in first use, so we see the content of the first tab, is there a possibility in tabview to make all tabs not checked, (for example : press second time in button make it not checked, and hide the main part of tab) ?
