Currently, there isn't an option to permanently get rid of the pop-up messages in QuickBooks Online (QBO), @GiantEyeRoll. Let me share further details about this.

The steps provided above are for the desktop version of QuickBooks. That's why they don't apply to your QBO account. The pop-up messages are ads that guide and suggest how to optimize your QBO experience. As of the moment, you'll have to manually close the ads or pop-up by clicking the "X" or "Close" button to prevent it from showing again. Please see the screenshot below for your reference.
