"invert shift" not supported by firmware

Using the browser-based Chrysalis, version 2024.0318.1913, and a Model 100 with firmware 0.92.6+116 which is the latest according to Chrysalis, I can’t use the “Invert Shift” feature, with an error message that “Your keyboard’s firmware does not include support for this feature”

Is there anything I can do to use this feature?
