Description

Adds RTX PRO 6000 BSE v6 GPU support for NAP/Karpenter by routing the RTX PRO SKUs to the NVIDIA GRID v20 driver image path.

Changes included:

• Adds GRID v20 driver selection for RTX PRO 6000 BSE v6 SKUs.
• Returns GPU_DRIVER_TYPE=grid-v20 for these SKUs so bootstrap resolves mcr.microsoft.com/aks/aks-gpu-grid-v20.
• Adds NvidiaGridV20DriverVersion = 595.58.03.
• Adds RTX PRO 6000 BSE v6 SKUs to supported-gpus.yaml as Ubuntu-only NVIDIA GPU SKUs.
• Preserves the existing CUDA and GRID behavior already synced in chore: sync GPU CUDA and GRID driver versions from AgentBaker #1705.
• Adds targeted unit coverage for driver type, driver version, image suffix, SKU recognition, manufacturer, OS support, and driver-install support.

RTX PRO SKUs added:

• standard_nc128lds_xl_rtxpro6000bse_v6
• standard_nc256lds_xl_rtxpro6000bse_v6
• standard_nc320lds_xl_rtxpro6000bse_v6

Important dependency

AKSGPUGridV20VersionSuffix is currently set to 20260101000000, matching the placeholder value in Azure/AgentBaker#8619. AgentBaker has not merged GRID v20 support yet, and aks-gpu-grid-v20 was not visible in MCR during validation. Replace this suffix with the real published MCR tag before merging if the final AgentBaker value changes.
