Safe to delete the Surface Hub 3 "admin" account?

We manage our Surface Hubs with Teams Rooms Pro (and Intune where needed).

The Windows default local administrator account is disabled during enrollment by the Deployment policy.

Intune is configured to add an Entra group to the Local Administrators group, whose membership we manage with an Identity Governance policy.

We are all set for administration. And if we were ever to be locked out of a Surface Hub, we would re-image it and begin again.

During the Out-of-box experience, a new administrator account named ".\admin", with a well-known simple three letter password, is added to Surface Hub 3 devices. Presumably, the account is added a "convenience". All my testing and research has shown that this account is not needed or used.

Is it safe to delete ".\admin" account? Or later, will I find Microsoft expected to use that account in some way?

Thanks, in advance.
