I am adding below line my INF:

[MyServiceInstall_AddReg]

HKR,Parameters,DmaRemappingCompatible,0x00010001,1 ; where 1 = opt-in

I do not see "DMA Remapping policy" in my driver details in the device manager even after this change.

Below is reference for how to enable this policy:

What is the way to further debug this ?
