How to enabling GuC/HuC for the i915 driver?

sudo cat /sys/kernel/debug/dri/0/i915_guc_load_status and sudo cat /sys/kernel/debug/dri/0/i915_huc_load_status shows neither is loaded.

Adding i915.enable_guc=-1 to the kernel cmdline results in blank screen on my Dell XPS 13 (9360).

Is adding i915.enable_guc=-1 (or 3) supposed to work? If so, how do I log of what goes wrong during boot without a working screen?
