ROG Strix RBG to RGBW LED swap

Hey all,

I have an ROG Strix motherboard with RGB lighting, and I would like to swap the LED's under located in this screenshot with RGBW LED's if possible. If an RGBW diode will not work with the guts underneath - I would settle with swapping it for a different RGB diode that emits a cleaner white.

I guess I just have no idea where to start with the disassembly, the areas I need to access do not appear to be accessible (no screws).

Is this something I'll need to carefully detatch with a heatgun or am I missing something obvious? Picture is below.

Thanks.
