Help with RAM's RGB

I bought my PC already built like two years ago. The RAM's RGB is not syncronized but I never worried about it. However, now i'm using it to watch series while i fall asleep so i need the lights off. I've got 2x8gb predator RAMs and my motherboard is a Biostar A520M (I KNOW IT'S HORRIBLE). So please does anyone know how can i do that?? Btw here are the rest of my specs in case they're necessary.

• Ryzen 5 5500
• Zotac RTX 4060
• My power supply is NFORTEC

PS sorry about my english as i'm spanish. 🙏😊
