  1. Remove the revisions property inside the supports parameter of register_post_type().

    Example

    $args = array(
    // ...
    'supports' => array('title','editor','thumbnail','comments','revisions')
); 
register_post_type('book',$args);

    Change to:

    $args = array(
    // ...
    'supports' => array('title','editor','thumbnail','comments')
); 
register_post_type('book',$args);

  2. If you don’t have control over the post type registration, you an use the remove_post_type_support() function:

    add_action('admin_init', 'disablew_revisions');
function disable_revisions(){
    remove_post_type_support('post', 'revisions');
}

    If you also wish to disable autosave for specific post types, you can do this:

    add_action('admin_print_scripts', 'disable_autosave');
function disable_autosave(){
    global $post;
    if(get_post_type($post->ID) === 'post'){
        wp_deregister_script('autosave');
    }
}
