Standard RGB Header Support? non addressable?

This isn't really an issue but didn't know how to contact otherwise.

I have a new ASUS mobo that I developing a variety of my own RGB stuff for... it does have an Adressable RGB header that which this library is working for me, and my own NodeJS is able to connect to using the information from here. Which is awesome, thank you!

However, the motherboard also has 2 additional RGB headers (non addressable)... and I can't figure out how these work... they should be easier since they are only just 1 color at a time.... I just need to find the right message/data format to send to them?

Do you know this?
