Hi Joy,
Is this the one you have tried ?
The “Let’s Finish Setting Up Your Device” message generally appears after you install an update and restarted your computer. It shows a message reminding you to “Finish Setting Up Your Device.” Windows stresses that you haven’t set up Windows Hello, Office 365, OneDrive, linked your phone to your PC, or synchronized your activity data between Windows PCs
Shut Off Reminders on Windows 11
The toggle to disable the reminder is also located in the Settings app on Windows 11. If you want to navigate there, go to Settings > System > Notifications.
You can also get there directly. Click the Start button, type “Notifications” in the search bar, and then hit Enter or click “Open.”
The Notifications page in the Settings app lets you control which applications can send you notifications.
Scroll all the way to the bottom. You’ll see two options: “Offer Suggestions on How I Can Set Up My Device” and “Get Tips and Suggestions When I Use Windows.”
Untick “Offer Suggestions on How I Can Set Up My Device.”
That pesky popup shouldn’t bother you anymore, though it is possible future Windows updates will re-enable it.
