I think you're likely to get a nutrient spike in terms of phosphate in most new reef tanks, whether or not you go to great lengths to cure/acid wash your dry live rocks.
I would just accept it and run a media reactor with GFO or another phosphate binding material from day 0. You can measure and tune this as you go.
I fear the issues with nutrient export many new tanks have are driven by this - not enough nutrient uptake from coral/livestock early on, combined with die-off/leaching from rock/sand. People upgrade they're nutrient export over time/delayed to the tank. This initial phase wears off and the sand/rock comes to nutrient equilibrium but now they have too much export/GFO for these things and strip their tank out.
There's no replacement for testing and matching your export/husbandry to match nutrient levels. Curing/acid washing rock doesn't completely solve this. I'd vote just plan for export, monitor and expect to ramp it down when your system hits equilibrium in 6-9 months.
