On TPM,  one way is to go to Dell's support pages, [URL] Let it recognise your machine's service tag and then go the driver and downloads. If you then search in the "Category" box for security, it might show firmware upgrades for TPM there if there are any.
is it possible to upgrade TPM from 1.2 to 2.0? is it possible to upgrade Intel CPU from old gen to 8th gen or newer?
