Thanks for coming back to the Community, @eeei732.
By design, the pop-up notifications are aimed to improve your QuickBooks experience. I understand that this is not always the case, and it would be helpful to have the ability to disable them. However, the option to disable them permanently is currently unavailable. The good news is, you can click on the X or No, thanks buttons to remove the pop-ups from your QuickBooks homepage.
Just because this option isn't available now, doesn't mean it won't ever be. I'm making note of this preference so our developers will know that this is something that they need to consider removing. We always appreciate the feedback on how we can make QuickBooks the best experience possible.
Please let me know if there's anything else I can assist with, I'm always here! Take care.
