How to disable drag-and-drop upload function in Media Library?

Does any one knows a valid/standard way to disable drag and upload when accessing the media library in the admin area? In order to make this sense to you, I’m building a multisite and user of sub-site cannot upload media files but they can view.

I can remove their capability ‘upload_file‘ but that would completely remove the media experience.

So far this is what I’ve got:

add_action('admin_init','disable_drag_upload');
function disable_drag_upload() {

    wp_deregister_script( 'wp-plupload' );
}

.. but that would skip the media library content.

Instead of removing upload script you can make the upload error out if the user does not have admin privileges. Like this-

function tomjn_only_upload_for_admin( $file ) {
    if ( ! current_user_can( 'manage_options' ) ) {
        $file['error'] = 'You can\'t upload images without admin privileges!';
    }
    return $file;
}
add_filter( 'wp_handle_upload_prefilter', 'tomjn_only_upload_for_admin' );
