Modify the BIOS on a Dell machine
Download Dell Command | Configure here: https://en.community.dell.com/techcenter/enterprise-client/w/wiki/7532.dell-command-configure.
Install it on one machine and make a copies of “C:\Program Files (x86)\Dell\Command Configure\X86” and “C:\Program Files (x86)\Dell\Command Configure\X86_64”. Use the cctk.exe tool contained in the folders to make your changes. You need the entire X86 or X86_64 folder as your source directory in SCCM, as it contains the driver the cctk needs to communicate with the BIOS.

If you do not have a BIOS password set, you can leave off –valsetuppwd.
