Also check the deflection at the top of your parapet due to the rotation of the stud wall. I have seen chimneys on a local project that has brick veneer for the chimneys supported in the same manner leaning inwards about 4 inches. But, these chimneys are about 8’ tall while your parapet is only a couple of feet.

I worked on something similar where you can support veneer without a ledger if it's limited to less than 15 psf. Beside that, deflection for gravity chould be kept to L/600. i could be way off though...

I have a situation where I have an exterior stud wall that is covered with rock veneer. The wall has a low parapet, just a couple of feet above the roof, where the veneer will also be located on the interior face of the parapet. I can't find anything in the IBC that would tell me I can't support the small height of rock veneer, on the interior of the parapet, by a ledger of some sort, which will be attached to the stud wall. 2304.12 tells me that I have to check the wood members for long term deflection. Is there any restrictions that I haven't found?
Thanks,
