how to list used libraries of a firmware build

is there a way to list USE_ defines set in .py file ?

eg PICO_R1_3.py

....
 'build' : {
   'defines' : [
     'USE_USB_HID',
     'USE_NET',
     'USE_GRAPHICS',
     'USE_TV',
     'USE_HASHLIB',
     'USE_FILESYSTEM',
     'USE_CRYPTO',
     'USE_TLS'
   ]
....
