It's very possible that OpenRGB could work. I have a question, though. Have you tried SignalRGB for yourself?

My motherboard (Asus) and GPU (PowerColor) are not specifically listed as supported, but still works. The ARGB header from my GPU is running directly to one of my motherboard's ARGB headers. With the motherboard's ARGB headers being detected by SignalRGB, the GPU LEDs can be individually controlled or altogether. My Lian Li Strimer cables nor their controller box are supported directly, but connecting the ARGB header from the controller box to another ARGB header on my motherboard allows me to control their LEDs as well.

SignalRGB just may detect your motherboard. If so, anything connected to its ARGB or RGB headers can likely be manipulated.

After being sick and tired of maintaining far too many manufacturer software solutions - Asus Armoury Crate, Cooler Master M+, Thermaltake RGB Plus, Corsair iCue, Lian Li L-Connect, and Razer Synapse. From launching multiple programs to their conflicts with each other, it became exhausting! So, I started using OpenRGB. It worked fairly well. After a couple of weeks, curiosity got the better of me, so I decided to give SignalRGB a try. All I can say is wow! Night and day difference. It's pretty amazing.
