Dell Command only does BIOS settings, doesn't it?  That's a different thing.  I tried that and I only saw stuff to set configs in BIOS.

I want to update all drivers and BIOS.

Command and Command Update are two different programs with two different functions from what I see

3.0 is very old now and 4.xx does not support older machines or older os.

Dell Command | Configure 4.X or later requires platforms supporting 64 bit WINDOWS 10 WMI-ACPI BIOS. 

NOTE: Dell Command | Configure 4.1 or later Supported Features Nomenclature (Names along with its Configuration Possible Value Names) have been changed across CLI and GUI. Dell Command | Configure even though is Backward Compatible for the Older Nomenclature, it is highly advisable to migrate/create Scripts to start using these Newer Features Nomenclature.

Fixes in the Release  4.2.1

Fix: Dell Command | Configure sets an unknown password for the BIOS issue has been resolved

Description: While running the following command

cctk.exe --setuppwd --valsetuppwd=abcd1234,

Dell Command | Configure displays Only validation option. No actions will be performed. Password is set successfully message issue has been resolved now.
