We don't monkey around your business.
Magento 2 comes with default shipping methods. But, if that’s not suitable to site owner then he/she can uncheck it.
Let’s see, how?
If you ever want to unchecked default shipping method at checkout or cart estimated shipping block, then it’s not necessary to create a module.
Of course, you can perform this task by creating a module. But, here we are showing you alternate method to do the task.
First step is to copy the js file checkout-data-resolver.js from vendor\magento\module-checkout\view\frontend\web\js\model
to app\design\frontend\Namespace\ThemeName\Magento_Checkout\web\js\model.
And then just find selectShippingMethodAction(ratesData[0]); and replace it to selectShippingMethodAction(null); in this function: resolveShippingRates
After doing such procedure you need to clear static content and cache.
That’s it.
