Everything in the '16 edition, chapter 10 deals with underground, and there is no such section.
If Jackie can apply the '22 edition, then your comment is spot on.

Item 2 allows 22" when the obstruction clearances of 10.2.7.2 can be satisfied which should be easy enough at a 2" difference in elevation.

I echo the thoughts of Anthony, Matt, and my good friend Cliff.
All the sections I note are from the '16 edition of NFPA 13
- Obstructed construction per §3.7.1, §A.3.7.1(1), as you have concrete beams, spaced between 3' and 7½" apart.
- Sprinklers required in each bay, per §8.6.4.1.2(3), as it's not possible to reach the 22" maximum in (1) or (2) as the beam depth is 24"
Hope that lines up with what others have to say. And, except for the section numbers this is fairly unchanged in the '22 edition.
sincerely,
