There's no 100% way until the new microcode is released next month. All affected CPUs are at risk of silicon degradation by the excessive voltage.

The are some power limits and July bios updates you can use that Intel says can help reduce the damage or prevent it entirely in some scenarios. I believe the damage is specifically caused by single threaded spikes, so reducing LLC and running something like prime95 in the background might hold the voltage low enough that it won't happen. But there is no fix yet, so if your CPU is susceptible, running it will degrade the CPU, at least until the fix is out.
