Hi,
Thank you for posting in Microsoft Q&A forum.
Per my experience, yes, we can use run command line task sequence step with cctk command to configure Dell BIOS settings. For example:
Cmd.exe /c x:\cctk.exe -setuppwd=***
For more information, here are some helpful articles for your reference:

Thanks for your time. Have a nice day!
Best regards,
Simon
