@David S ,
In general, Teams Rooms will get update automatically. If you don’t want to wait for it, you can follow the normal procedure for Microsoft Store for Business to Distribute offline apps.
Download deployment kit here. Then, run the installer. Once finished, it will open the folder where it has been extracted. You can now run an elevated PowerShell session on the Admin desktop side of the Microsoft Teams Room system. The reference document is here.
For more details, please refer to Graham Walsh’s blog.
