Ok, the one you found is on:
Settings > Advanced > AMD Overclocking > AMD Overclocking > Precision Boost Overdrive

Try to look at:
OC > Advanced CPU Configuration > Precision Boost Overdrive

Core Performance Boost is the XFR option. Once you disable that option the CPU only runs at base clock speed (3.6 GHz for your 3600.)

Isnt XFR the former name of PBO?
XFR (eXtended Frequency Range) bacame PBO (Precision Boost Overdrive)

Core Performance Boost is another name for PB (Precision Boost)

PB and PBO are 2 different functions

No, not on a MSI motherboard, CPB is XFR renamed. You can disable PBO, and leave CPB on for the advertised XFR boost (4.2 GHz.)

Just my two cents in this. Overclocking is and always has been about going over the specs and limits that the manufacturer has set. Zen2 is no different, except maybe for the headroom being very, very slim. I wouldn't worry one bit about going over the stock PPT, TDC and EDC limits. I am willing to bet (though can not prove, just like anyone outside AMD can't) that those are not set primarily for the silicon longevity, but for product segmenting. If 3600 was somehow substantially more fragile than for example 3600X, that would make Zen2 a very special case in the history of silicon chips. More likely is that the limits for the 3600 are set lower primarily because of the smaller stock cooler.

FIT is another thing, and that I would keep an eye on. As the Stilt has stated, the best way to get to know the guideline for the limits of your own chip is by removing PPT, TDC and EDC limits, keeping all other things at stock and putting the processor under load. And that load should be the heaviest load that you are going to be putting on the CPU when actually using it. For my own 3600, that is 1.313V (the lowest I've seen a core dip to under gaming load). And since my CPU/MB combo doesn't want to boost too well and I can get 4.2GHz stable at 1.297V, my choice is all core. If I did actual heavy stuff, I'd have to go for ~1.25V to feel comfortable.

Even for FIT, there is bound to be a certain buffer that AMD has seen fit (pun intented) to leave between FIT voltage and quick degradation. How big of an gap it is, we don't know. Most likely very small compared to pretty much any previous CPU we've seen. But still: going over PPT, TDC and EDC limits is nothing to worry about. FIT is relevant and a good ballpark to what you should set for voltage. And overall, gains by all core OC are very small but not completely irrelevant. Most gains are from IF and memory tweaking.
