Missing UEFI Boot Path Security on Dell Precision 3620

Question

So we are in an academic environment, and to protect our machines, all of them have a BIOS password enabled. We also 'thought' this would automatically enable 'UEFI Boot Path Security' with 'Always, Except internal HDD.' However, that option does not exist on this machine. We verified this on about 20 machines.  The funny thing is, the option is available on a Optiplex 9020 and a Precision 3640. Even on a Precision 3630, the option was added via a firmware update and was placed under DellSmbios:\AdvancedBootOptions. Is there any way to set this option for the 3620? How is it that it is on an older machine, but not this one?

UEFI options on these Precisions can feel oddly inconsistent. BIOS updates sometimes hide or reset security paths without warning, especially after switching boot modes. Clearing TPM or loading factory defaults brought missing entries back for me. Double-check Secure Boot is actually enabled, then re-add the boot path manually. Dell firmware loves burying important toggles behind one wrong setting.
