OSD Module

Make sure that your OSD Module is at least version 21.7.11.1. Once you have that, you can use Get-MyBiosVersion to check your current BIOS version
Installing Firmware Drivers will require Admin Rights, and make sure you have your Bitlocker Keys backed up and that you suspend Bitlocker before any updates

Before going any further, its important to understand what the Windows Firmware update platform is. Enjoy the read and come back when you are up to speed

Device Manager

Taking the information from the Microsoft Windows UEFI firmware update platform link, you can see that (on Windows 10) the System Firmware is in Device Manager. Digging into the Details provides a value for the Firmware Resource ID
You can get this information from PowerShell using Get-CimInstance
Or use two new OSD Functions to provide this information

Microsoft Update Catalog

Finally you can take the System Firmware Resource (Guid) and run a search in Microsoft Update Catalog and you should be able to find the matching UEFI Firmware Updates for your system. Just select the newest one and download the CAB

Remember about suspending Bitlocker first!
