You're asking about using PBO on your 5700X3D. It's true that X3D chips aren't fully unlocked and can't handle high voltage, which limits overclocking. PBO isn't about overclocking but giving the chip more power. Whether it's safe depends on your setup—don't expect damage if done correctly, but always check compatibility first.

Higher power limits and voltage are distinct concepts. Power equals voltage multiplied by current, and current depends on clock speed during specific tasks. Raising the power limit enables faster clock speeds, regardless of voltage changes.

The only adjustments possible for AM4 X3D chips involve curve optimizer (using PBO2 tuner) and BCLK modifications. You can't exceed a maximum load voltage of around 1.2v because it's built-in to handle that, mainly for safeguarding the 3D cache. Generally, you'll find yourself with about 102 BCLK plus an additional 84mhz clocking into the core, which is typical. For optimal performance, try keeping clocks slightly lower via PBO2 tuner so games run smoothly, and consider tuning the RAM for reduced stutter.

It's not accurate to say changing the voltage is entirely up to the motherboard. You can adjust it to higher values if needed on those chips. However, because the multiplier is fixed and overclocking BCLK on X3D chips isn't practical, you usually don't need to modify the VCore setting except in very specific cases. The standard voltage will never exceed 1.2V.

Using Curve Optimizer is recommended. These CPUs are constrained by power limits and multiplier caps, making PBO ineffective. You might bypass these restrictions by adjusting current telemetry data in BIOS, though this won't significantly impact gaming performance.

However, the clocks are also affected by temperature, meaning more power usage increases heat output. In scenarios like X3D, you're likely to face greater thermal stress, which could cause clock regression or stretching—making it unwise unless you have excellent cooling. It won't help with gaming performance either, since these chips consume extra power during gameplay. This becomes significant in heavy workloads such as Linpack Xtreme or OCCT, though even Cinebench might notice a difference if the cooler isn't strong enough.
