Aorus Xtreme Waterblock can be bought separately?

I’ve been looking almost everywhere to buy this [waterblock](https://www.gigabyte.com/Graphics-Card/GV-N5090AORUSX-WB-32GD) made hy Aorus Gigabyte for the Xtreme Waterforce line of GPU’s for [my 5090 AIO Xtreme Waterforce](https://www.gigabyte.com/es/Graphics-Card/GV-N5090AORUSX-W-32GD). Safe to say that there’s no official retailer that sells this waterblock without including the GPU itself with it.

Is there any other way to get hands in this waterblock? Or should I just give up and buy the Alphacool Aorus Master waterblock? Not sure if this is the best waterblock for this model, but I think it’s compatible since the Xtreme Waterforce AIO version of this card shares the same PCB as the Aorus Master.

Tried to talk to Gigabyte support to see if they could hand me the waterblock if I paid for it but sadly they didn’t agree to this. GPU is the only component left to cool on my custom loop, I could keep the AIO but it kills the aesthetic of the build and the cooling is not that good as if I incluse it in the custom loop.
