Hello Miguel Diaz,
Thank you so much for using our theme Education Base Pro. Please check the video blog to know how to reduce the height of that section. You can get the options to manage the header part size on the customizer. Kindly check all the options there. If you want to completely remove that part, you need to add the below css codes to hide that section. Add the css on Appearance > Customize > Additional CSS.
.wrapper.inner-main-title {
display: none;
}Thank you
