Building for EFI

Hello,

I am greatly interested in trying pick up work on MicroV and in particular need to build for EFI for my project.

I have an Ubuntu 24.04 (x64) and also want to test loading of Windows 10/11 and Ubuntu 24.04 guest OS once it all build but there is not much information on EFI building that I can find so far.

Can you please assist?
Thanks
