Not without the ACS override patch, Intel really did a disservice to device
assignment users with how they've combined more devices into multifunction
sets on skylake and didn't bother to implement ACS.  We've had confirmation
that some of the I219 NICs are isolated and we have quirks for them, but
apparently not this one.  There's little hope of getting anyone's attention
to verify whether the audio function is isolated.  Thanks,

Alex
