I might not have the answer regardless, but I can tell you that you haven't given enough information to start with.

Whomever gives you an answer will need to know what hardware you are using. Airspy, RTL Dongle, SDRPlay, something else? If an RTL Dongle, are you sure it is one that built-in bias-tee support?

The --args parameter is passed to the driver, so just set it as needed for your hardware on the command line and it will go through.

Not sure what you mean by above response can you give a example of what you mean.

OP25 RTL-SDR V3 and Biast

Hey, Using Ubuntu 18.04, rtl-sdr V3 with OP25 to decode P25p2 and it works great. I've noticed that I can't use the internal bias tee of the V3 with OP25. Every time I activate bias tee and start OP25 it turns the bias tee off. Any thing I can do about that besides dumping the internal bias...
