There is a way to improve the sound, but it’s not automatic.
Audacity has a new tool called Punch Copy/Paste.

You need a copy of clean background sound—room sound or Room Tone without breathing. Then drag-select the breath sound from the show and punch clean background sound over it.
Do that for every breath.
I ran into this because I have noisy breathing (gasp) during (gasp) announcing.
