NanoVDB headers have unused code using "double" type, which is not supported on Arc GPUs. Recent DPC++ changes enforced runtime verifications: https://github.com/intel/llvm/commit/7663dc201de253ae876b6f3989818feffb299ea1 which prevents execution when such type has been present even if unused. This is a solution to avoid double to be compiled at all, similar as how it is done for Metal.
