What is the best way to update values in a pandas data frame using values from a different data frame?

I have two data sets with varying sizes. I'm trying to substitute values in one dataset (df1) with values from another dataset (df2). I've tried looking for an answer on this platform, but I might not be articulating the question correctly. Any assistance would be greatly valued.

This is what I aim to achieve.
