Does WITH_NVME/WITHOUT_NVME do anything at all? The only mention of WITH_NVME in the code is in camcontrol.c and it's defined in the makefile in CFLAGS as -DWITH_NVME. Looks like nvme support is determined by kernel configs — adding 'device nvme' and 'device nvd' to sys/arm64/conf/GENERIC was enough to enable the drivers on aarch64…
