Hm… Strange I was very much of the opinion that I had the option, when I bought the laptop, but (at least on mobile) I can’t see it now.
Because I remember, that I was so happy to be able to choose CoreBoot

But checking my BIOS, it’s from insyde
And I’ve no idea what exactly those guys are and what they build up on - or if it’s a completely other UEFI BIOS

That’s a bit of a bummer now, actually

Edit: or maybe I’m mixing it up with the StarLabs StarFighter order, I had to cancel.
That would make at least sense, and my memory is just scrambled, but not completely creating fictional stuff ;⁠-⁠)
