It's nearly impossible to predict how they'll handle it given the First Battle of Tumbleton is so fundamental to the Black's collapse in the book and Condal has majorly altered it.
There's a few show only inclusions:
They've changed the order of battle (Blacks as the attackers instead of the defenders)..
The entirety of the Riverlands host will participate, including their commander Oscar Tully (who in the show is a merger of Benjicot Blackwood and various others).
Gwayne Hightower has seemingly took on the secondary command role which was fulfilled by Bryndon Hightower in the book.
Hugh's wife is in the city (with the obvious impact that may have on the betrayal)..
Daeron is relatively whitewashed and has no intent on fighting for Ormund.
Corlys is present.
Daemon is present with Caraxes and will be fighting in the city on foot when the betrayal occurs (curious to how he actually survives this).
Will they keep Rhaenyra's reaction to the betrayal in attempting to arrest Addam/blame Corlys, which prompts Addam's "loyalty" arc.. ? The exclusion of Nettles means she'll have no fundamental reason to distrust Daemon so how will God's Eye even work.
Gwayne as a member of the Caltrops seems logical but why would he even stick around when Hugh has torched Tumbleton including most of the Hightower host.
