Unable to update BIOS automatically in Dell Command Update ADMX in Intune
I’m currently facing an issue where I cannot deploy BIOS through Intune Dell Command Update admx. I have already set a static BIOS password on each clients. Since I couldn’t find any option in the DCC ADMX to enter the existing BIOS password, I tried alternative methods.
I tried installing Dell Command Endpoint Configure for Microsoft Intune on the client and creating a configuration to deploy a CCTK file. The CCTK file is very simple:
[cctk]
AdminSetupLockout=Enabled SetupPwd=<existing BIOS password>
However, when tested on a machine, the BIOS still cannot be updated automatically.
May I ask if my approach is incorrect, if there’s another method to update all client BIOS, or if I might have missed a step?

Did you import ADMX files to configure the settings? I am working on this at the moment but can't update the ADMX files. I think you need to import them and then configure the settings (like GPO)

I’m not sure about the details of your issue. In my case, the root problem was that I was trying to update Dell devices through Dell Command Update, but the BIOS password field was greyed out.
The solution is not to apply the CCTK file. The CCTK file is used to manage the BIOS password directly, not within Dell Command Update.
You need to run a PowerShell script to set the BIOS password specifically for Dell Command Update, not through CCTK:
"C:\Program Files (x86)\Dell\Commandupdate\dcu-cli.exe" /configure -biospassword="your password"
After that, you can configure the Dell Command Update ADMX template to schedule updates daily, weekly, or monthly for more control.
