Encrypt Device - Policy Wizard

In the Policies startup wizard there is an item Encrypt Device under Restrictions. When I enable this and then look at the policy created, I can't find this item again. We only manage Android and iOS devices via SMC. Is this setting only possible for Windows or macOS and I don't see it in the Android/ iOS policies because of this?
Unfortunately I did not find anything in the manual.
