You have to de-solder it. Optionally (in case you don't want to remove the part, since it will be difficult to reinstall it), you could install a jumper (zero-ohm resistor) or (better) a small 10pF capacitor in parallel (there is a pad), but this may cause some weird side-effects if you use the USRP in the ISM band after installation.
