I believe the issue is not about eliminating the ^M characters as
such. The program is clearly using the CR character to overwrite its
earlier output. Jean probably wants to obtain that effect in an Emacs
shell buffer — seeing only the last string output to a line.

To achieve that, I’d probably try adding a font-lock pattern of .*\r
and fontify it with an invisible face.
