Just a note, this needs to be `ROG Zephyrus G14 GA402R` or this will
catch the GA402Q series as well which doesn't require this quirk.

In general the model numbering goes
<Range><Model><Generation><Graphics>, So for my old G14 <GA><402<Q><M>.
Or for example a ROG Strix machine <G><513><Q><Y>

I don't know of any others that may need this quirk.
