RatOS - Unknown pin chip name 'vref_scaled'

I currently have my 3D Printer up and running mainline Klipper with a Duet 6HC v1.02. Today, I started testing to see if I could migrate to RatOS even though it does not officially support the Duet series of boards.

I copied over my (almost entire) working configuration to the printer.cfg file (this includes a board_pins mapping).

Unfortunately, I am running into an error saying Unknown pin chip name 'vref_scaled'

Here are my configuration sections that utilize verf_scaled:

[board_pins duet3_6hc] mcu: mcu aliases: temp0=PC15 # VSSA Sense vssa=PC13, # VREF Sense vref=PC0,

[adc_scaled vref_scaled] vref_pin: vref vssa_pin: vssa

[heater_bed] sensor_pin: vref_scaled:temp0

Any idea why it is causing the error?

But regardless, you're going to need features that don't yet exist
