how can i remove all discord nitro notifications on my PC application?

you see, the problem is that i am currently living in Russia, i'm already understood your hatred about everyone from this country, because i get this notification when ANY new version of this feature are going online, and i am getting this annoying banners about "yo, look how our new feature looks, cool right? buy it"
i WILL BE happy to, in case if i can buy it legally, but when i click on it this banner says that i can't because of my birth place, you see, it's not my fault for being birth somewhere or in this time, and this makes me VERY annoyed and angry any time when i see banners like this, so yeap, can i remove it? in any possible way?
currently Discord is only way how i can communicate to my friends, and i used to love this service, but now it looks like a spit on my face, and i am very dissapointed about that
