No. CW can be handled by selecting as small a bandwidth as possible. SSB on the other hand is much more difficult. That's where all the proprietary schemes come in.

algorithms for this with many manufacturers having their own
proprietary algorithm ...

Do any of the DSP NR algorithms or schemes favor CW?
