[MCU] Could Doctor Dtrange have done a time loop to Thanos like he did with Dormammu?

I’m a bit of an MCU newbie so I don’t really understand how the stones work but couldn’t Doctor Strange have done a time loop at any point during one of Thanos’s attacks and just reset the loop until the Avengers manage to defeat him?

No.

Notice that in all the iterations, Dormammu never tried to yank the Eye of Agamotto from Dr Strange? As a timeless being, Dormammu cannot really grasp the concept of time, so he probably isn't even aware of the time stone, let alone use it.

Thanos on the other hand knows exactly what the time stone is and how to use it. In the first loop, Thanos will just grab the stone, and then undo the loop.
