Answer 1

For Material Google Library:

TextView snackbarActionTextView = (TextView) snackbar.getView().findViewById(com.google.android.material.R.id.snackbar_action);
snackbarActionTextView.setAllCaps(false)

And for Support Design Library:

TextView snackbarActionTextView = (TextView) snackbar.getView().findViewById( android.support.design.R.id.snackbar_action );
snackbarActionTextView.setAllCaps(false)
