Enabling or disabling Infinity Fabric Power Management

Enabling or disabling Infinity Fabric Power Management
When Infinity Fabric Power Management is enabled, the EPYC processor dynamically varies the clock frequency of the Infinity fabric
based on activity levels.
For NUMA optimized workloads, allowing the Infinity fabric to run slower may lead to an increased overall performance due to an
increase in the CPU boost. Disabling this feature may be necessary for latency sensitive workloads.
