The Apple USB-C to 3.5mm Headphone Jack Adapter (05ac:110a) is a
headphone DAC with no S/PDIF | IEC958 connector; its only output
terminal is of type Headphones (0x0302). Add it to the blacklist to
prevent it being opened, so PulseAudio and PipeWire stop offering a
"Digital Stereo (IEC958)" profile for it.

The card name is "USB-C to 3.5mm Headphone Jack A", but card_name
replaces the '.' with '_' (as with the "USB Device 0x46d_0x821"
entries), so the entry has to read "USB-C to 3_5mm Headphone Jack A".
