How to Remove Shipping and Payment Steps from Checkout and Directly Enable “place the order” Button?

[Snake]

Hi Bagisto team and community,

I’m customizing the checkout process in my Bagisto-based store.

Objective:
I want to remove the shipping and payment steps from the checkout process entirely. That means:

• On the checkout (buy) page, once the billing address form is filled, I want to directly show and enable the "Passer la commande" (Place Order) button.

• I want to remove the "Continue" button and the intermediate steps for shipping and payment.

• Essentially, the customer fills in their details, and can immediately place the order without additional steps.

This is intended for a simple store setup where no shipping method or payment choice is required (I have one shipping and one payment steps).

Could anyone guide me on the cleanest way to achieve this in Bagisto 2.3.6?

Thanks in advance!
