Sophos Encryption / Tablet RegEdit

We are noticing a requirement to activate Sophos encryption via registry edit for tablets like the Microsoft Surface. The need is to add registry entries to enable BitLocker authentication for devices that lack keyboards in the preboot environment (such as tablets).

This is also a valid addition for other manufacturers, such as Dell, Lenovo, and others. We already had a script to add. Would it be possible to add the registry to the configuration task or a pre-req script along with the Sophos Endpoint Agent software deployment.
