Audacity has such a feature. It works quite OK, given, you do not overdo
it. It can add some phasing and tends to make the overall sound somewhat
murky so one needs to fiddle a lot with the preview before applying it...

You first select a noise-reference in you file, then call  the
noise-remover and tell it to use the selected audio as a noise-sample.
Then you select a range you want to clean up and start fiddeling with
the (few) settings ....

best of luck ;-)
