This new feature of the latest update has created a very specific problem that I was lucky to detect. Now, the correction of TWo INitial CApitals Works even when the word is not present in any dictionary. The problem is that I work with technical documents which very frequently use the term Megahertz (MHz) or Gigahertz (GHz).

I don't want to discard this feature as it's mostly useful, but I'd like to skip it for certain cases such as this one. Is there any change of doing exceptions or autocorrections for these particular cases, or the only way is to configure a regular expressions check?

This is a case where the intention of a new feature is good but the consequences are somewhat unexpected. The nomenclature of measurement units might créate problems with the choice of ignoring whether a word is in a dictionary in order to enforce this automatic correction feature.
