The above solution was not working.
I think i found a better way of achieving what i was looking for:

function update_featured_post() {
  
  global $posts;
  global $post;
  
  // Get other post marked as featured
  $posts = get_posts([
  // Array of posts to check  
  'post_type' => ['post', 'evento'],
  'meta_key' => 'post_em_destaque',
  'meta_value' => true,
  'post__not_in' => [$post->ID]
  ]);

  // Remove previous featured posts
  if ( get_field( 'post_em_destaque' ) ) {
  	foreach( $posts as $p ) {
  		update_field('post_em_destaque', '0', $p->ID);
    }
  } return;

}
add_action('acf/save_post', 'update_featured_post', 20);
