The RockPro64 doesn't have a Mali 400 (Utgard) GPU, it has a Mali T860 (Midgard). I recommend installing the Debian packages for Mesa 20.3.5, which includes the Panfrost open-source driver that work pretty well to drive the GPU. The specific package names are libgl1-mesa-dri, libegl-mesa0 and libgbm1, though installing any OpenGL(ES)-using package will normally bring them in as dependencies.
