Great question! The short answer is yes, but the method you’re familiar with from AMD 10h series CPUs won’t work here.

Let me break down the details clearly:

• On AMD 10h series CPUs, you can programmatically disable hardware prefetch by toggling a specific bit in the MSRC001_1022 MSR register.
• Unfortunately, this MSRC001_1022 register doesn’t exist on 17h series CPUs. To find the correct way to disable prefetch on these chips, you’ll need to refer to the official AMD 17h series processor programming reference manual, which outlines the appropriate MSRs or configuration options for this purpose.
