Can i remove cash flow from appearing in dashboard screen

Thank you for posting here on the Community page, mkpaul1974.

I have some insights to provide regarding removing the new cash flow graphic from the dashboard in QuickBooks Online. 

Currently, the option to remove the cash flow graphs that show up on your dashboard is currently unavailable in QuickBooks Online.I know that being able to customize your dashboard will be convenient for you in organizing your data. I'd like to inform you that your developers are collecting and considering new functions to be added to the system to meet our customer's needs.

To submit feedback, you can go to the Gear icon and select Feedback.

Stay tuned for upcoming updates. If I can help you with anything else, please drop me a reply below. Have a good one.
