one way to do this is via the Teams Admin Center, in your M365 portal.
Navigate to Teams Devices\Phones, you should see a list of all your phones there, you can click on a phone to see various details. You can update some/all of the phones via that Teams Devices\Phones.
There may be other ways to do this too, but that is how i manage my phones
