I am not sure even LT and Thanos /w IG could take a hit from the UN by just shielding up and amping durability. Redirection might be neccecary to avoid nullification even for them.
If you mean during the ig saga I think thanos had his regular durability until the big guns showed up like the celestials and stuff...
Unless you think something making you the level of eternity allow you to be hurt by someone like Thor.

Well during the ig saga he had fought all the normal heroes... Then the abstracts with his dials up to ten....
Then reset time and said this time I'll turn my dials down a bit... Considering how they faired and the fact tht he knew how it was gonna turn out...
