TPM firmware update

Hello all,

Has anyone been able to successfully create a process that will perform a TPM firmware update against Fujitsu, HP & Lenovo machines as it appears to be quite a complex undertaking due to the fact that it isnt simply a matter of running an EXE, due to drive enyrption having to be disabled beforehand, ensuring the machine isnt running on the battery, disabling sgx & vrt, setting tpm policies so that they do not prompt when an update is taking place, clearing the tpm afterwards, not to mention requiring tpm owner and bios super user passwords? 

Thanks in advance,

SK.
