lol, sure no. if DEX asks a documents, from that moment it becomes CEX

literaly, how can they check your documents without centralizing?
for me it is even strange when exhcanges ask KYC for small amounts or cryprto-crypto trading.
The data must be stored somewhere else in the cloud, that itself obviously cancels out the very purpose of being a dex which purpose is to make sure that there is no one storing the client data.
Maybe the government law forces them to do so but nonetheless might aswell off being a centralized exchange instead.
