I can see the importance of blocking the bank feed pop-up rules in QuickBooks Desktop, @shiner. I'll ensure to provide you with an alternative solution to your concern.

We can check the "Don't ask me again - just create rules automatically" option below. Doing this will prevent it from popping up again in the future.

Also, you can uncheck the Create rules automatically and Always ask before creating rule options if you don't want to auto-create a rule.

Here's how:

1. Go to Banking.
2. Select Bank Feeds.
3. Choose Change Bank Feeds Mode.
4. Under BANK FEEDS, uncheck the Create rules automatically and Always ask before creating the rule.
5. Once done, click OK.
