The Java shops you're thinking of didn't disable GC during working hours, they just sized the generations to avoid a collection given their normal allocation rates.
But there were / are also plenty of trading shops that paid Azul for their pauseless C4 GC. Nowadays there's also ZGC and Shenandoah, so if you want to both allocate a lot and also not have pauses, that tech is no longer expensive.

Well, I just trivialized it. However, in one case in mid 00s, I saw it disabled completely to avoid any pauses during trading hours.
