+1 on the need to set the Supervisor PW in BIOS, otherwise the settings were greyed out. Puzzling indeed, I had to deal with it back some 5 years ago. Definitely found this answer on forums rather than from mfgr suport pages/docs.

However in this case it may be a different "lockdown" issue, though quite an odd choice reasoning-wise.

With this machine, if purchased from Amazon, the settings remain greyed out even if you set the Supervisor PW. That is not the case if you buy it elsewhere.
