How do we clear the TPM of Intel NUC D53427RKE

Hello,

I am trying to clear the TPM of a D53427RKE NUC so I can take ownership of it. I am using the latest BIOS version for this model (34).

After entering maintenance mode in the visual BIOS there is a checkbox "Clear Trusted Platform Module", but no "OK" button.

If I press F10 to save the setting and exit the TPM is still not cleared.

Thanks in advance.
