Simple Delivery is not compulsory..... yet, so you can opt out if you wish. I believe you'll need a laptop / PC and use Chrome for this, not the app or mobile browser.
When creating a new listing here's how to opt out:
Click on Custom Postage option, this is next to the simple delivery option on the listing on the right hand side, and it should allow you to then select your postage options.
