FreeBSD won't boot on the MoreFine H1/AMD Ryzen AI Max+ PRO 395

I tried versions 15 RELEASE and 16 CURRENT. The result is always the same: the system lists the PCI devices and then stops at some point. See the linked video for details. mp4
Can this issue be effectively resolved by changing the BIOS settings, or do I have to wait for full system support for this processor version?
So far, for the past two years, I’ve been using version 14 on an older model from this company, the MoreFine M600, with an AMD Ryzen 9 7940HS and a Radeon 780M GPU, and everything works flawlessly there…
 
I noticed another strange issue: the “o” key doesn’t work in the boot loader command line. All the other keys work fine. So I couldn’t run the “boot -v” command ;-)
Fortunately, the keyboard shortcuts worked. I booted the system with the “verbose” option enabled. See the attached video for the result: Boot -v.
 
I checked all possible settings; the results are shown in the table below:
ACPI
Safe
Single

The “Fail” symbol indicates that the boot process has stopped with the message “AcpiOsExecute: task queue not started”.
