How can you tactfully drive away a relative who eats, drinks, and lives all the time?

You can tell him that you are going on a long trip, and then arrange for the whole family to go together. In this way, I think all relatives know what is going on, and it is time to leave other people's homes and not stay in other people's homes all the time. .

Or you can express your difficulties appropriately and let him know your difficulties. I think generally if others have difficulties, relatives will understand.

If you really don’t encounter those ignorant people, there is nothing you can do.

I can only say it clearly to myself. Sometimes if you really bother others when you see them being inconvenient, I think such people are boring.
