Expanding the bass frequencies, (i.e. those below ~200Hz), will make drum & bass more prominent.
Audacity does not have a native expand-dynamic-range effect, but I know of 3 free expander plugins …
“La Petite excite” … Fine Cut Bodies | Sound Design,
It’s the simplest to use of the three: (first try turning up “low” knob).
“Cramit” … Cramit | Free Multiband Compressor With Distortion [VST3 only].
The arrows pointing away form each other = expanding.
“ToneBooster’s FIX V3” [VST2 only] … Free (v3) ToneBooster's plugins - #2 by Trebor
The most complicated of the three.
