AFAIK for the GPU the situation is usually not that bad (many/most ARM SoCs use Mali GPUs nowadays and these are fairly well supported under GNU/Linux). I'm not familiar with the situation with NPUs but indeed, I wouldn't be surprised if those aren't usable without SoC-specific proprietary drivers and blobs :-( This said, never say never: back when I got my BananaPi, a Free Software GPU driver for its Mali GPU seemed "impossible", yet that's exactly what we have now.
