How to change Store Street Address from required to optional

I invite you to read https://docs.drupalcommerce.org/commerce2/developer-guide/customers/addr..., you should find what you need there.

@jsacksick Thanks for your prompt reply. I know how to add and configure the address module, while the Address Field in Store type is not configurable. I looked at the commerce_store_field_data in the database, the street field is optional, but it is required in the form display. That's why I ask how to change it.

I know it's not configurable, but there are example of codes you can find there... besides, support requests aren't answered from this queue if you paid attention to the guidelines...

With the abundance of support available in Drupal Answers, the Drupal focused Stack Exchange site, we are no longer answering support requests in the issue queue.

Support requests opened here will be closed (won't fix), so please search for existing answers or post new questions at:
