"Always On" Jumper missing on Nanosound DAC Case

I’m a long term Argon 40 case user, so I was surprised when I got my Nanosound DAC case and it was missing the usual jumper to configure the case to be ALWAYS ON.
I really need this feature as I cannot turn on the case via button/remote (its part of an automated continuous integration pipeline).

Is there a way to have the ALWAYS ON functionality without a corresponding jumper?
