More details regarding TPM can be found here

"Removal of Trusted Platform Module (TPM) 1.2: VMware discontinues support of TPM 1.2 and associated features such as TPM 1.2 with TXT. To get full use of vSphere features, you can use TPM 2.0 instead of TPM 1.2."

Resolution

Engage the hardware OEMs to upgrade the Trusted Platform Module on all affected hosts to a supported TPM version. (2.0 or higher)
