Cause
This is expected behavior, Intel Platform Trust Technology (PTT) is enabled by default on the Latitude 7350 which causes the "TPM Security" option to be disabled, since both TPM and PTT cannot be enabled at the same time.

- Tap the F2 key when the Dell logo appears to enter the BIOS
- Expand the "Security" section, click "PTT Security", and deselect Intel Platform Trust Technology
NOTE: If PTT is greyed out as well, re-enable PTT by disabling Intel Trusted Execution under Virtualization Support.
- Click Apply and Exit to reboot

- Expand the "Security" section, click "TPM Security", and select TPM Security
