How to remove an author's photo in blogger?

[Valmirpn]

Hello everyone, I'm using the Gameify-templateify theme and I want to remove this photo of the author that appears above the post and put a little icon in the place of the photo. Please help me, I want to remove only the author's photo and not his name

With CSS:

.author-avatar {
   display: none;
}

This code also removes the editor's photo in the footer, as I wrote, I want to remove only the image above the posts and not all the author's images. I want to remove only this top part that I marked
