Not to say I don't trust your post I'm replying to, H.G., but as they say, 'trust but verify'...
A not-too-old answer I saw when I Googled 'Does Stockfish use piece values', as found on 'Quora':
'In chess analysis, computer tools like Stockfish, Komodo, and AlphaZero help us know the importance of each chess piece during the game. They use calculations to assign a value to each piece based on factors like mobility, king safety, and board position...'(12 Sep 2023, Tato Shervashidze, Chess Coach...)
If that's true, such computers are actively doing 'calculating' of their piece values (rather than relying on e.g. statistical-studies-generated ones that are generalizations), on a position-by-position basis in a given game that they are playing.
That's also rather than by using piece values calculated before the start of any play whatsoever, say in the sort of way Betza tried to calculate fairy piece values (or my own cruder way(s) of estimating such values, i.e. in quick and dirty fashion).
