It should be the same code for the in-game stuff, I think.
You could always disband the templars and still get to experience that side of the story 
Not sure about the tutorial (maybe try the options menu), but fun fact: Cullen was actually going to be a romance option for both male and female humans and elves, and it was cut due to time. That said, you can pretty much flirt with everyone (aside from I think Solas?), regardless of gender and restrictions. Like Cassandra. Even when she they don't feel the same 
*looks at the Approval ratings*
Barris: But the Order is leaderless, gutted by betrayal. We must rebuild it.
Rebuild as our partners. (Ask the templars to join you as free allies)
Blackwall Approves
Cassandra Greatly Approves
Iron Bull Greatly Approves
Sera Greatly Disapproves
Solas Greatly Disapproves
Varric Slightly Approves (only if he was brought for the quest)
Vivienne Approves
Then yield and serve us. (Convince the templars to disband and become part of the Inquisition instead)
Blackwall Disapproves
Cassandra Disapproves
Iron Bull Disapproves
Sera Greatly Approves
Solas Greatly Approves
Vivienne Slightly Disapproves
Hmmm, that doesn't sound bad

(lit the only one,
who I care about, who doesn't approve is Cassandra)
And I get Cole

my baby

I tried that (searched through the options) but couldn't find anything Tutorial related =/
Awww, how mean!
Cully & my Lavellan would be so cute. (when I'm gonna romance Cullen, I'll romance him with a mage
)
