Hey I came across this software from what appears to be a chinese developer called uefi bios editor. I downloaded it but as I'm still learning everything about modding bios I'm sure I don't know how to use everything in it. From what I can tell using it , it uses what uefi tool,ifr extractor, hxd and mmtool all rolled in one. Seems pretty convenient and I haven't tested yet but you may be able to do an actual edit on the ifr text file and have it apply to the dxe directly. I mean you still have to extract a module out and open it in the tool but there is no separate extraction to view the text.
