Our services icon change

Greetings!!
It’s amazing this theme you have in enigma.
I search for the topic, “replace our service section icons with images”. I found one but i has no answer at all. I don’t know if this is because somewhere the documentation says that that’s not possible. But I wish that where possible and to get an answer.
Could you help me? this is actually my first post, my first enigma and wordpress page, I even don’t have a site yet, I’m working in my lap…
