How to add space between header and section

You can use the lv_obj_set_style_pad_row(sub_mechanics_page, 10, 0);.

lv_obj_set_style_pad_row(sub_mechanics_page, 10, 0); is working, but header top spacing also increases. Is it possible to adjust header top spacing?

Could you send a small code snippet to demonstrate the issue?
In the original snippet from the first comment create_text is a custom function.
