Trezor and wasabi coinjoin are the same thing. Just take one coinjoin is on wasabi and the other is on Trezor wallet with the help of wasabi that are working in conjunction with Chainanlysis to sensor transactions.
Have you read about Jointmarket before:
https://en.bitcoin.it/wiki/JoinMarketagree, an alternative to wasabi - trezor - samourai is JoinMarket;
Joinmarket is a peer-to-peer system that allows users to increase the privacy and fungibility of a Bitcoin transaction through a process called "CoinJoin." In a typical Bitcoin transaction, a sender transfers a specific amount of Bitcoin to a recipient, with this event being recorded on the blockchain. However, with CoinJoin, multiple users' transactions are mixed together into a single transaction, making it difficult to determine the origins and destinations of funds.
SOURCE--but there is also another alternative (I don't really understand how it works), it's called Liquid Network;
Launched by Blocksteream in 2018, Liquid Network is a layer-2 sidechain that improves the performance and functionality of Bitcoin. With Liquid, users can complete fast, secure, and confidential transactions on the Bitcoin blockchain.
