Hide Advanced Layout Builder button for blog posts only

Hi,

I only want authors to use the Classic Editor (installed plugin) for normal blog posts. Which is why I would like to hide the ALB editor for editors and authors, but just for normal blog posts. The button should remain available for Pages and Portfolios.

I thought I had found a solution with the code below, but that hides the button everywhere.

// Hide Advanced Layout Builder button
// >>>>> HOW TO RESTRICT THIS TO JUST THE NORMAL WP POSTS?
add_action('admin_head', ' hide_alb_editor_button');
function hide_alb_editor_button() {
  echo '<style>
    #poststuff #avia-builder-button {
      display: none;
    }
  </style>';
}

So, is it possible to restrict the hiding of the button to just the blog posts?

Thanks for your help and have a good day,
Rob
