Enable disk encryption for "Compliance exclusions" (#26476)

- @noahtalerman: I'm using a test Windows computer to write a guide
about disk encryption keys (more info
[here](https://github.com/fleetdm/confidential/issues/9031)). This
Windows computer isn't used for work so we want to add it to our
"Compliance exclusions" team so it doesn't show up in Vanta compliance
reports.
