Windows 10 and 11 automatically take ownership and provision the TPM. See the following excerpt from the documentation:

About TPM initialization and ownership

Starting with Windows 10 and Windows 11, the operating system automatically initializes and takes ownership of the TPM. This is a change from previous operating systems, where you would initialize the TPM and create an owner password.

The default Windows configuration ensures that delegated authorization information is available in the Windows Registry. TBS.h exports functionality that can be utilized to retrieve these delegated authorization values.

Access to this functionality is not currently implemented in tpmutil.
