I am using a ETH full node server (geth) with RPC Server to operate some operations in server side (Generate wallet, send transaction). I would like to generate USDT wallet for my users but I coud not find any good documentation on this.
Do you know how to create a USDT wallet from ETH NODE RPC ?
There is no such concept as "USDT wallet" - you have made up that yourself.
Any Ethereum address can receive any token.
