Maybe the situation has changed recently, but as I understand there is no scholarly consensus on when plate tectonics started and it is the topic of active debate. For example Onset of Plate Tectonics (2011) https://www.science.org/doi/10.1126/science.1208766 says:

> The further back we look into the geological past, the more obscured the view, masked by an increasingly fragmentary geological record. This has resulted in a controversy on whether plate tectonics operated the same way, or even at all, during early Earth history.
