MetaBox extension installed via composer

Hello,

Is there any possibility to prevent extension generating a registry in autoload_files.php?

I'm using modified version of bedrock and because it's calling autoload early, some plugin can't recognize and use native WordPress function so I have to use them as mu-plugins.

Base MetaBox form wpackagist doesn't generate registry in autoload_files.php but any extension does and it generating some errors in PHP like:

Uncaught Error: Call to undefined function add_action()
