Came across this custom DIVI tab style.

Divi tab style


You will just need to change the CSS Class to: icon-tabs

Paste this code in the custom CSS:

.et_pb_tabs.icon-tabs {
border: none;
}
.icon-tabs ul {
margin-bottom: 30px;
}

.icon-tabs .et_pb_tabs_controls li {
border-right: none;
}

.icon-tabs ul.et_pb_tabs_controls {
background-color: white;
}
.icon-tabs img.alignleft {
margin-right: 70px;
}
.icon-tabs .et_pb_all_tabs {
border-top: none;
}

.icon-tabs .et_pb_tabs_controls {
padding: 0 10% !important;
}
.icon-tabs .et_pb_tabs_controls li {
width: 50% !important;
}
.icon-tabs .et_pb_tabs_controls li a {
width: 100% !important;
text-align:center;
color: #a3a3a3;
text-transform: uppercase;
letter-spacing:2px;
font-weight: 600 !important;
}
.icon-tabs .et_pb_tab_active a {

}
.icon-tabs .et_pb_tab h2 {
