Each FIM and FPM installed in a FortiGate-7121F includes a Trusted Platform Module (TPM).
You need to enter the following command to enable TPM support and input the master‑encryption‑password once from the primary FIM. You don't need to enter the command separately for each FIM and FPM and you do not need a separate master‑encryption‑password for each FIM and FPM.
config system global
set private-data-encryption enable
