I don't have gnuradio-3.8 installed any more, but I do still have
the .grc gr-soapy YAML file for my RSP1A which I used then, and that
definitely has a properties configuration entry for the soapy block
which in my case is "sdrplay_biastee: 'False'", and (as the OP is also
interested in the MF/VHF notches), similar entries for
"sdrplay_dabnotch" and "sdrplay_rfnotch".

These are not present in the YAML file for the built-in soapy block
provided by gnuradio-3.9.1.0 and later.  To provide a RF notch with that
one I had to supply a device argument of "rfnotch_ctrl=true", along the
lines of the one you have suggested above for bias tee.

So how you do it seems to depend on which version of gnuradio and/or
soapy block you are using.
