Lockout from features happens on medical hardware - I’ve seen it regularly on MRI scanners from Siemens, GE and Philips. Send them money and the feature gets unlocked.

Some options are less expensive, some more. The most expensive I’ve seen is US$50k for enabling a feature. They do it then you restart the system to enable it.

I know of a physicist who used to be able to unlock some things, but now there are much more elaborate security measure.
