I found the following resources helpful to me with the same issue.
https://developer.apple.com/metal/tensorflow-plugin/
https://stackoverflow.com/questions/70315694/vs-code-install-tensorflow-on-mac-m1-mini
I don't think either suggested solution worked on its own for me, but the combined info in those posts helped me figure it out for my particular environment.
UPDATE: I found another guide that another person posted in the comments here...it seems to be helpful as well:
