According into this link and seeing top post.
It is supported but not through its own wallet interface yet you have to use a third party wallet interface but dw your coins will still be ON the Trezor. You will just have to look, send and receive the coins through another interface. Go to Trezor Coin List and it’ll show you what wallet interfaces are available for each coin

https://trezor.io/coins/Raven could be stored in Chaintek , Electrum-RVN , Mango Farm.
Yes, I see that, but not sure how to actually setup the linkage from these wallets to Trezor, was hoping there was something going through the process step-by-step.
