Are we sure about that? As far as I know, the show hasn't even officially been greenlight, and is in the same will-they/won't-they- limbo as ST4 (although with much better chances at the moment).
Like, Ash Tyler appearing there is just fan speculations, isn't it? The only thing confirmed is "Michelle Yeoh", and she's currently in the far future. Apart from that, it's "earliest after DIS season 3", and "scripts are being written, but no production has started".
I know this is purely speculation on my part: But IMO it sure as hell looks like they are giving the 23rd century up entirely - and focussing on Picards era & whatever they put DIS in. I guess neither "Lower Decks", that animated kids show, nor S31 for that matter will be set in the 23rd century anymore, even if that might have been the plan at some point in the past.
