**Description**
Azure pipeline cpu-unit-test failed for "2025-12-10T03:47:59.0628597Z
ERROR: Could not install packages due to an OSError: [Errno 28] No space
left on device"

**Root Cause**
This happens because the matrix jobs (Python 3.7, 3.10, 3.12) run in
parallel and share the same VM's disk. Python 3.12 downloads
newer/larger packages (especially PyTorch and NVIDIA CUDA libraries
which are ~3GB+), and when multiple jobs run simultaneously, they
exhaust the disk space.

**Fix**
Disable the cache usage when installing SB
