Are there any crypto exchange making services?

Is it possible to create a CEX exchange (without KYC and regulation) or DEX exchange with the help of site making services that would be understandable for a beginner without knowledge of coding
CEX is centralized, meaning it conforms to the regulations of the government, so there is not going to be any CEX without KYC
