Unfortunately, there is no 'setting' to hide View All link at this time. Because, when you click this link, it will take you to All Items and as per the product team's response on this idea, you cannot hide the "All Items" label at this time
An admin can however hide all of the "Items" in "All Items".
To hide items from the App Launcher individually, one should follow the steps below
- Go to Setup
- In the Quick Find bar, search for Profiles.
- Select the Profile you want to remove items for.
- Click Object Settings in the App Settings.
- Select the Object Name you want to remove items for in the App Launcher.
- Click Edit.
- Change the Tab Settings picklist value to Tab Hidden.
- Click Save.
- Click Object Settings in the breadcrumbs.
