Yes you can, add this in your style.css child theme:
.header-content-wrap {
background: rgba(0, 0, 0, 0.5);
position: relative;
-webkit-box-shadow: 0px 5px 11px 0px rgba(50, 50, 50, 0.08);
box-shadow: 0px 5px 11px 0px rgba(50, 50, 50, 0.08);
padding: 285px 0 410px;
}
Change the 410px in what you want to resize the section
