That said, I think DSC was produced with the idea of giving the franchise a visual facelift, irregardless of the continuity errors, so there's probably no in-universe explanation that will work perfectly. Beyond just declaring the canon broken now, I think we're left with either assuming that the Disco-prise is the one true version of the Enterprise pre-movies or that it should be considered artistic license along the lines of recasting an actor and that the two are "really" the same thing.
The Powers That Be have been pretty inconsistent on whether the DSC tie-ins (and the PIC, as well?) have any canonical value, depending on the interview. My interpretation is to count them until the TV show contradicts them (although some of the novels have gone out of their way to reconcile discrepancies with the TV show). Not saying I'm right, but that seems to be the only position that makes sense, all thing considered.
The closest they've come to addressing the Disco-prise was a throwaway line in the Enterprise War novel, which mentioned that the ship had been refitted for the special mission of the book (the novel takes place during DSC Season 1 and leads right into Season 2). It's not perfect (for example, it doesn't account for all the remodeling of the interiors), but it was an explanation. Unfortunately, the Short Treks episodes ("Q&A," "Ask Not," "The Trouble With Edward") showing the Disco-prise in a pre-"Cage" setting, making a refit explanation highly implausible. (The animated short "Ephriam and Dot" does show the Disco-prise with the TOS interiors, among other pieces of artistic license, so I kinda think the short isn't meant to be taken too seriously, least of all since it's implied to be an in-universe short film).
On the other hand, DSC did contradict itself on the Disco-ized TOS uniforms (in Season 2, it's mentioned that they're a new design, but we see them in the Short Treks episodes set years before), so the flip-flopping between refits isn't an unique problem.
Long story short, I think it's best to understand that DSC, PIC, SNW, Prodigy, and possibly LDS (although they revel in continuity of all kinds) are being made under the idea that they don't have to match up everything 100% and that accidents to do happen even with the best of intentions (compare the Short Trek "Calypso" to DSC Seasons 3 and 4). It's just a TV show franchise after all, not a divinely-inspired holy book.
