Hi Ben,
What do you mean by Render Settings? Quickly scrubbing through this Lesson, I think Kent just changes the Output to 300% and that hasn’t changed. In fact, I don’t think the Render Settings have changed that much since 2.93.
Are you perhaps talking about the Subsurface Scattering in the Principled Shader?
If so, set the Weight of the Subsurface Scattering to 1 and play with the value of the Scale. You might also benefit from changing the method to Random Walk (Skin).
If you mean something else, please be more precise and also give a timestamp as to where in the video you get into problems.
