Hi Deekshith,
I'm Sumit, here to answer your query at the Microsoft Community.
Yes, the TPM must be cleared after recovery. Please press F12. TPM stores the PIN hashes, but as the data was removed from the drive i.e. the PIN data, the TPM must be cleared.
Hope that helps, and rely on us for any further inquiries. If you have no other questions, you can close the thread and rate it. All the best.
