This kind of thing is not new. In 1998 I worked for a large corporation (I think they were an F100 at the time) that built machines with a feature that could only be enabled if the customer paid an extra fee and had a field technician come out to "install" it.
Unknown to the customer was that all machines were identical. The technician's "installation procedure" was to enter the Service Mode password, select the feature enable option, and exit Service Mode then run a test to make sure it worked.
This is pretty common in commercial/industrial manufacturing. The exception cost to omit certain hardware subsystems when building a product is often higher than the cost of the hardware itself, so it makes more sense to build everything identically and enable/disable features in software.

If you want to see the way this looks on the flight displays that a pilot sees, this video shows some examples (generated from a flight simulator): https://youtu.be/L5KQ0g_-qJs?si=AtYkellEROnHZ89e&t=349
