To enable Shared computer activation you should have Office 365 E3, E5 or business premium.
If you want to enable shared computer activation during the initial installation of Microsoft 365 Apps, you can instruct the Office Deployment Tool to do so during installation.

Licensing token renewal The licensing token that is stored on the shared computer is valid only for 30 days. As the expiration date for the licensing token nears, Microsoft 365 Apps automatically attempts to renew the licensing token when the user is logged on to the computer and using Microsoft 365 Apps.
Activation limits Normally, users can install and activate Microsoft 365 Apps only on a limited number of devices, such as 5 PCs. Using Microsoft 365 Apps with shared computer activation enabled doesn't count against that limit.
Licensing token roaming Starting with Version 1704 of Microsoft 365 Apps, you can configure the licensing token to roam with the user's profile or be located on a shared folder on the network. Previously, the licensing token was always saved to a specific folder on the local computer and was associated with that specific computer. In those cases, if the user signed in to a different computer, the user would be prompted to activate Microsoft 365 Apps on that computer in order to get a new licensing token. The ability to roam the licensing token is especially helpful for non-persistent VDI scenarios.
