What are these headers on my z790 Hero Maximus?

 Anyone have any idea what these 2x headers on my Z790 Hero Maximus are? They look like USB 2.0 but aren't labeled on the board nor is there any mention of them in the manual. Or anywhere else on the web for that matter. 

 

Posted everywhere, this is my last hope! Anyone?

I have them on my board, but no idea what they are for. I don't use RGB so figured that's what they were, but manual doesn't show them.

 

I still have no idea what they do. I plan to pin them out when the system is fully built. ASUS mods have been of no help, on both this forum and on reddit. 

 

Literally noone has had an answer for me. I figure they are for board diagnostics at the time of manufacture but thats a geuss. The weirdest part is our boards are unique in having them. There are many Z790 Hero Maximus' that don't have them at all. 

 

I'm still searching for an answer. @asus anyone listening??

Almost certainly something for manufacturing or servicing the boards.  They could be something like JTAG or some sort of serial port used for board setup or diagnostics in the factory.  They are undocumented, and looks like they are unlabelled on the board, so not for normal end-user usage.

Hello, @Breeze23 

I apologize for the delayed response.
We have established after consulting with the relevant department that the motherboard region you marked is a dedicated header used by our service engineer for further diagnostics.

Thank you.
