You can try this

(define-minor-mode hide-^M-mode
    "Minor mode to hide ^M."
  :init-value nil
  :lighter "hide^M"
  (setq buffer-display-table
        (and hide-^M-mode
             (or (get 'hide-^M-mode :table)
                 (let ((table (or (copy-sequence standard-display-table)
                                  (make-display-table))))
                   (aset table ?\^M [?\u00A0])
                   (aset table ?\^I (vector (make-glyph-code ?\^I 'underline)))
                   (put 'hide-^M-mode :table table))))

and then setting hide-^M-mode in the mode hooks.
