DSDT Patching help

Heya!

I am trying to patch my DSDT but I couldn’t help but notice there are a few definitions used that are not used on my present DSDT in the modding guide found here: DSDT Patching · xCuri0/ReBarUEFI Wiki · GitHub

Most I did a small search and found made sense like M1MX is RMAX on my mobo, however I couldn’t help but notice TUUD is not defined at all on my motherboard. What are some other letterings TUUD could have? Does it matter?
