Fails to install on Nvidia DGX Spark (and other ARM devices)

Executing nix-env -iA nixgl.auto.nixGLDefault as written in the readme errors with:

Following the article linked in #150 mentioned by the issue above, I tried nix-env -i -E '(_: with import <nixgl> { enable32bits = false; }; nixVulkanMesa)', which installs, but doesn't seem to work with proprietary nvidia drivers nor lavapipe. I've been testing with the wgpu test suite, which seems to detect lavapipe and read it's limits and features (thus disabling some tests) but actually initializing a device seems to fail.

Combining the two, I tried nix-env -i -E '(_: with import <nixgl> { enable32bits = false; }; auto.nixGLDefault)':

Any ideas where to proceed?
