I use naturalReaders.com to read documents and books. It’s not Morgan freeman but you do get to select which voice actors from a list you want to read the words. Different accidents and tones. I switch voices to help with retention and differentiation of documents.

Give it a try. Could they make a Morgan freeman version, easily. But legally, I’d like to think some things are respected and sacred. But you could do a similar voice in terms of confident and calm.
