Hide the OneDrive and SharePoint app tiles
By default, the OneDrive and SharePoint app tiles appear in the app launcher and on the Office 365 portal. If your subscription doesn't include one of these services, or if you don't want users using one of them, you can hide the app tile for it.
Hiding these services doesn't remove them for users. If users have saved the address of the service, they will still be able to access it.
If users click a tile for a service they don't have, they will see an Access Denied message.
To hide app tiles
Sign in to https://admin.microsoft.com as a global or SharePoint admin to open the Microsoft 365 admin center. (If you see a message that you don't have permission to access the page, you don't have Office 365 administrator permissions in your organization.)
In the left pane of the admin center, under Admin centers, select SharePoint to open the SharePoint admin center. (You might need to select Show more to see the list of admin centers.) If this opens the new SharePoint admin center, select Classic SharePoint admin center in the left pane.
In the left pane, select settings.
In Show or Hide Options, choose the tile you want to hide.
If you have an Office 365 Education subscription, you also have the option to hide OneNote Class Notebooks and OneNote Staff Notebooks.
> Hiding the OneDrive tile also hides the Office Online tiles (Word, Excel, PowerPoint, and OneNote).
Select OK to save the settings.
