Can I use both GD and Imagick drivers simultaneously in Intervention Image

When you create an instance of the `ImageManager`, you need to specify which driver you want to use:

php
// Use the GD driver
$manager = new ImageManager(new Intervention\Image\Drivers\Gd\Driver());

// Use the Imagick driver  
$manager = new ImageManager(new Intervention\Image\Drivers\Imagick\Driver());

You cannot create an `ImageManager` instance that uses both drivers at the same time. The drivers are mutually exclusive - you have to choose one or the other.

The reason for this is that the two drivers have different underlying implementations and capabilities. Allowing both to be used simultaneously would add unnecessary complexity and potential conflicts in the library.

Instead, you should choose the driver that best fits your requirements and system setup. Imagick generally provides better image quality and format support, while GD is simpler to set up. The decision should be based on your specific needs and the tradeoffs you're willing to make. But you can only use one driver at a time within your Intervention Image-based application.
