Hello... Of course, there is software available from Gigabyte for this purpose. This is called "RGB Fusion 2.0".
But beware, this program is the same as rubbish. If you are lucky, you can set all your RGB of the mainboard without problems, but often this program causes problems. Go to Google and see how badly RGB Fusion 2.0 is written. I'm still having problems at the moment too. I set the RGB, then at some point it doesn't work again, or the graphics card is no longer recognised, etc....
Hello Yes, of course, you can download the app from their homepage, Appcenter (https://www.gigabyte.com/Motherboar...) RGP Fusion, which is included, can be set specifically to RGB, via this program you can then control or set everything.
