Configuration file no longer applied after updating to 0.5

I have a configuration file, ~/.config/wireplumber/main.lua.d/51-disable-dock-audio.lua, with the following contents:

rule = {
  matches = {
    {
      { "device.name", "equals", "alsa_card.usb-DisplayLink_Belkin_USB-C_Dock_10127776-02" },
    },
  },
  apply_properties = {
    [ "device.disabled" ] = true,
  },
}

table.insert(alsa_monitor.rules, rule)

As of updating to 0.5, this configuration file no longer functions. The device is not disabled, which breaks sound on my laptop.

I do understanding that Wireplumber no longer loads these lua files as of 0.5 but I cannot find any guide anywhere about how to migrate configuration.
