If you intend to use PiHole, why is your DHCP server configuring a non-PiHole DNS server?
And why would you expect the pre-boot environment to respect OS network configuration?
Just like every non-Apple system I’ve ever seen with pre-boot network support, it has its own configuration, which defaults to DHCP.
I’d honestly be more suspicious if the firmware tried to grovel through OS data to find a working network configuration you may not want it to use.
Not that it would have very good luck doing so on a security-conscious user’s system, given that, on most systems at least, pre-boot networking is configured long before encrypted boot volumes are unlocked, since at that point you’re already well on your way to booting a specific OS and the pre-boot networking envieonment is no longer required).
