This is not a problem because it is possible to use full platform name,
which includes a profile name, as a dependency.
The ubiquity driver checks some flags before enabling hsr, but I can't
still track down where they store them. May be somewhere in eeprom.

I like this idea because in this case it'll be much easier to correct
problems or add changes.
However for more general use a patch to the driver is much better.

I have a couple photos of pcb (one with annotated serial port), can send
them if you need.
