@Andy92 add this code at the end of your CSS file (Themes → Assets → theme.css)

@media only screen and (min-width: 769px) {
  .promo-grid--space-bottom {
    padding-bottom: 0;
  }
  .promo-grid--space-top {
    padding-top: 10px;
  }
}

Add this rule to the bottom of theme.css

.promo-grid {
  padding-top: 10px;
  padding-bottom: 10px;
}

#shopify-section-162687279350ae426c{
  margin-top:0px
}

Result:
