590.48.01/DCGM 4.6.0-1 was never a deliberate compatibility choice — the driver version traces back to a CDN 404 on the originally pinned 550.54.15 (commit559fc29), and DCGM was bumped twice since purely because NVIDIA pulled the previously-pinned core package from the repo (6dee8f3,b2e177a). The 590 branch only has two point releases so far, and its nvvs plugin fails dcgmi diag with "Detected driver major version 0 is not between the required versions 346 and 2000" on H100 — confirmed via a staging support bundle. Switch to 580.126.20 / DCGM 4.5.2-1, the combo NVIDIA's own DGX OS 7.5.0 release notes validate for H100. Both packages confirmed present in the NVIDIA CUDA debian12/x86_64 apt repo.
