Kerberos SDR activate noise source in python

I do have a KerberosSDR that I would like to use with python (using PyRTLSDR). How can I turn on/off the noise source in Python? Could someone help me with the requited code to write the on/off byte?
Many thanks!

The noise source is controlled by GPIO 0 on the first RTL-SDR. To keep things simple you can just flip GPIO 0 on all tuners, as the other GPIO’s are unused.

In pyrtlsdr you can flip GPIO 0 using the set_bias_tee command. e.g. sdr.set_bias_tee(true)
