Changing BIOS Passwords Remotely

Hi everyone

I am a new Helpdesk Analyst within a company and have been given a task to find a way of changing all of the BIOS passwords within the company, preferably remotely for obvious reasons. There are approx 250+ machines with the majority of laptops being Dell Latitude and workstations Dell OptiPlex although most of the laptops have BitLocker activated.
We also use Empirum software to push out software to the machines if this would be of any help.

I have been looking around and into using the Dell Client Configuration Utility and also the OpenManage tool although I'm not too sure if they would work for us due to us using BitLocker.

Any help would be much appreciated.

Thanks in advance.
