Apple - How can I stop iPhone prompting me to setup Apple Pay in Settings?

Choose the option to finish setting up your iPhone, then choose Set Up Apple Pay. On the following screen, under Continue, choose Set Up Later in Wallet.

If you are in a region where Apple Pay Cash is supported, go to Wallet & Apple Pay in Settings, then disable Apple Pay Cash.

1. Go to Settings app → Wallet and Apple Pay.

2. Turn off Apple Cash.

3. Go back to Settings app main screen and go to the notification about setting up Apple Pay. Click as if you’re going to set it up, and then click on set up later.

4. You then have to go back into "Wallet and Apple Pay" and again turn Apple Cash back off as it was turned back on.
