Hypothetically what would it cost currently to 51% attack Ethereum for 1 hr?

I know when Ethereum was POW it was kinda straightforward to quantify a hypothetical 1-hr 51% attack cost (Bitcoin supposedly would currently cost $1.3 mil/hr). Is there a number for Ethereum now after switching to POS?

Obviously I know it’s all hypothetical but it’s just interesting to quantify these things on some level
