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

Since upgrading iOS to 11.2.1, my iPhone has aggressively prompted me to setup Apple Pay. Every time I decline to set it up. Now, there is this persistent badge ("1") on my Settings app, which makes me think there is some kind of iOS update to install, but instead, it is a prompt to setup Apple Pay ("Finish Setting Up Your iPhone"): How can I turn off prompts/notifications/badges asking me to setup Apple Pay? This is not the same as disabling Apple Wallet notifications, as asked and answered at https://apple.stackexchange.com/questions/256991/disable-apple-pay-wallet-spam . Disabling Apple Wallet notifications does not disable the Apple Pay spam (specifically, the Settings badge icon). This question is different as it is about Apple Pay and the Settings badge icon (not notifications specifically), and the solution in the purported "duplicate" question does not solve this problem.
