Update BIOS

Hi,

How can we use DCU to manage our BIOS updates?

We plan to update our BIOS firmware on 100s of laptops. We currently have a GPO to configure all of the DCU settings and set it to automatically download and install all driver updates. We have 'BIOS Updates' enabled, but you can't set the BIOS password (wouldn't want it set in the registry either). This means BIOS updates aren't managed. Is it possible to get BIOS updates working this way?

If not, we have SCCM so perhaps there are some good ways using that, but we don't want the password recorded in plain text
