PBO2 5000 series compatibility?

So I was looking at how to undervolt the Ryzen series and it seems like it can be a bit of a pain in the ass and can eliminate your boost stuff, so you get better economy but wrecks your peak performance.
Then I find a video showcasing PBO2, basically a BIOS option that can allow you to optimise your power curve but done by the system rather than you, thus keeping the boost potential.

What I found amazing that under no load you get less heat and draw, yet under load, due to the power cap being the same the curve just lowered, it optimises the frequency x voltage. Guy showed it topped out at about .2gz higher clocks on the same volts and temps. On single core it got similar boosts yet 7c lower temps. Which is amazing. I know this info is vague, but it's not what I'm here for.

He stated his brand new ASUS 570 (insert long as name for top of the line here) mobo did yet have the BIOS update to allow for PBO2, Yet one of the similar MSI boards did have that update.

My questions are:

1. I'm getting the R7 5800H 3070 A15 Tuf Dash, is there any way to find out if PBO2 is compatible with that mobo?

2. If it isn't yet, is there a way to find out if they will be rolling out that BIOS update and will it be throught windows or a reflash?

3. Where does that stand in terms of warranty, because the user is not overclocking the chip, you're optimising the power curve and the software basically uses everything at it's disposal all on its own?

Asuming the H series have same functionality as the desktop ones I don't know (anyone?), you don't need a special mobo, only one with recentish bios. Undervolting can often have you reach higher clocks due to thermal limits, but it might be irrelevant now in terms of max clocks since most boards have capped manual OC to +200 instead of +500 for PBO2 for now, in which case you will definately reach the max boosts. PBO2 is better than stock setup, lower temps higher sustained boosts, its very straight forward too, just follow the infograph AMD put out for PBO2. Its not going to break anything.

Bios flash done in bios, should be on Manufactors website, follow guides pretty straight forward nothing to fear its not the 90's.

With this being a laptop it might mean that you don't have all the tweaking options that a desktop motherboard would have. It will depend on how much Asus have left open to the end user.

The manufacturer website would be your best bet, especially if they have a support forum of their own.

Pass. I would think that you'd be covered, because even PBO has hard-and-fast limits that it won't send a CPU beyond.
