Not with the ENT cast, since that show was cancelled and branded a failure. Hence Enterprise and Archer being namedropped as missing the opening of the war since they were ar Risa. They wouldn't have spent money developing a Romulan war movie (even if it wasn't made) if someone didn't think it'd make money.
Fact remains, we at least have some idea as to what Archer was doing between 2155 and 2245. And we have some tidbits for Sato too. And T’Pol, Phlox (and his Rigelian parrot), and maybe even Mayweather should have lived long lives as well. Plus, Reed is supposed to be considered a larger-than-life hero. And what Trip was doing back then remains ambiguous. And Porthos was as well known as the rest of the crew. There’s nothing stopping Discovery from at least referencing:
- Sato & first contact with the Atianna (from the ENT novel Rosetta)
- the Ware crisis (the repair station from S2),
- Sato and the rest of the ENT crew served under Captain T’Pol on the Columbia class USS Endeavour
- Archer bringing Rigel into the Federation
- Archer being the one that pushed for the Prime Directive to be established
- the crew’s stay at Risa while Columbia was present at the Battle of Sol
Barring that, some deleted scenes - like Sim mentioning that Vulcans used to have a lifespan of 40 years, or Valdore and the Romulan Senator being taken into custody for his failed drone war - are certainly more canon when compared to literature or unused scripts.
And reference that the Utopia Planita Ship Yards were supposed to be in existence in this time, since there did not seem to be much of a shipyard from what we saw during ENT. It would also make for a subtle connection to PIC as well.
There’s quite a bit of worldbuilding DIS could do for ENT with a reference here and there while still building their own as well.
With the superweapon DMA, considero Kal Dano, inventor of the Tox Uthat. He was smart enough to invent a hand-held weapon that could destroy a star, seems like this would be up his alley. He might have been alive at the time of the supposed battle of Procyon V.
And back to that Enterprise era connection..

I don't think that DISCO writers are necessarily actively dipping into STO continuity, but still, that could very well be Kal Dano.
The DMA could be also be related to the Sphere Builders. Or the Triannon, who created a religion around the spheres and anomalies.
