How to disable all optional modules in Magento 2.3?

Question

I want to disable all third-party modules and Magento's optional modules, for example, DHL, Klarna, Temando, Vertex, etc.

I disabled via admin panel and CLI

There is a different way to exclude them?

Answer 1

You can remove them via Composer.

You could install the Yireo module:

composer require yireo/magento2-replace-all:2.3.1

OR

You might be able to specify the packages to be removed in your composer.json and running composer update.

Examples

Remove all third-party core modules

"replace": {
        "amzn/amazon-pay-and-login-magento-2-module": "*",
        "amzn/amazon-pay-and-login-with-amazon-core-module": "*",
        "amzn/amazon-pay-module": "*",
        "amzn/amazon-pay-sdk-php": "*",
        "amzn/login-with-amazon-module": "*",
        "dotmailer/dotmailer-magento2-extension": "*",
        "dotmailer/dotmailer-magento2-extension-enterprise": "*",
        "klarna/m2-payments": "*",
        "klarna/module-core": "*",
        "klarna/module-kp": "*",
        "klarna/module-ordermanagement": "*",
        "temando/module-shipping-m2": "*",
        "vertex/product-magento-module": "*",
        "vertex/module-tax": "*",
        "vertex/sdk": "*"
    },

Remove all optional core modules

"replace": {
    "magento/module-advanced-pricing-import-export": "*",
    "magento/module-amqp": "*",
    "magento/module-analytics": "*",
    "magento/module-authorizenet": "*",

Answer 2

On my travels I've come across ths blog post

https://www.integer-net.com/make-magento-2-small-again/

But it makes sense what's been disabled

I haven't had the courage to do the full list but certainly I've removed the third party extensions from this list
