Default icd file consists configuration only for PCIe-1433, 1435 and 1437 frame grabbers. With NI Camera File Generator you can easily create a new config file.
Second thought - Basler spL4096-70kc can operate in 8 taps mode (8-bit depth). At the same time, PCIe-1433 can work in 2 taps mode (max 12-bit depth, see link below). After adding new target frame grabber in NI Camera file Generator you will notice that throughput will be automatically limited to 2 taps.
