Enemies to lovers, with the enemies part done properly
The trope has one rule and most tools break it in the first chapter: they have to actually be enemies. Not mildly irritated. Not bickering for the reader's amusement. Rivals for the same promotion, opposing counsel, the man who bought the building her family used to own. The hostility has to cost something, and it has to be sustained long enough that the first crack in it feels like a betrayal of everything both of them have said. That is what enemies to lovers readers mean by a slow burn: not a delay for its own sake, but a change of mind that has to be argued for, scene by scene, against real resistance.
A story engine can only do that if it remembers the resistance. The insult from the second section has to be still in the air in the ninth. The thing she swore she would never do has to be a thing the story knows she swore. If the model has forgotten by then, the turn is unearned and the reader feels it before she can say why.
How DesireBorn holds the tension
Before writing, DesireBorn builds a plan: where the story is going and what each section is for. Then it writes one section at a time and carries a story state between them. That state records what has been established about the two of them, what each has said and cannot take back, which threads are still open and what has been set up to pay off later. It is what lets a late section refer to an early one without you having to remind the engine.
The turn is the part you will probably want to steer yourself. After every section there is a field where you can tell the story what should happen next: make him lose the argument, put them in a room neither can leave, let her be the one who blinks first. Or leave it blank and let the engine choose the moment. Readers who like to be surprised by where the burn finally catches can do exactly that.
Setting it up
One line is enough. "Two rival chefs are forced to share a kitchen for a season" gives the engine the enemies, the proximity and the clock. Add the people if you have them in mind, or let the story introduce them. Choose a point of view if you care whose head you are in; enemies to lovers is often best in alternating close third, but the choice is yours and can be left open.
The themes in the catalogue that readers of this trope reach for are Slow burn romance, obviously, and then Rough, Forbidden affair, Strangers and Dominance, depending on how the power runs between them. Tick what matters, leave the rest.
An example
"You are standing in my light."
"It is my kitchen."
"It is your name on the lease." She did not move. Neither did he, which was new. For six weeks he had always been the one to step back, with the small tight smile that meant he was counting the days. Tonight he stayed where he was, close enough that she could feel the heat off the pass behind him, and when she finally looked up he was not smiling at all.

What the story is allowed to be
Enemies to lovers runs on friction, and friction between two adults can be as sharp as you want it. Contempt, cruelty, a hate-fuelled first kiss and a second one that is worse: all of it is fiction between adults and all of it is fair game. How explicit the scenes are is a setting you control, from closing the door to staying in the room.
There is one limit, and it does not move. Every character in a sexual context is an adult. It cannot be turned off, softened or configured, by you or by us. No shame. Not no limits.
