Windows 10 Building a Tool to Access All Firmware on Device

[ExylonFiber]

I am attempting to write a tool that is able to read and write firmware on any hardware device that has firmware. I cannot find any resources on YouTube, Google, or the Windows Developer API. Is it even possible to access any firmware on the Device?

How can I find all the firmware on my device and extract it from each device?
