After I outputted a binary file of the ACPI dump, I found a few key errors
after querying the binary, using strings raw_acpi.bin | grep -Ei

I also found more potential issues when querying the binary file using strings
raw_acpi.bin | grep -Ei "PNP09|VGA|LCD|IGPU|GFX|CON":

VGA_M291

I have attached the binary file as well, in case there are other queries that
can be conducted that I haven't thought of.

Of other note: Using this information, I attempted to disable a few ACPI
aspects to further debug the issue. These attempts unfortunately did not
improve the condition of the device. Of other note, the ACPI issues have spread
to the desktop environment, which no longer displays on boot and cannot be
started via commands like startx. The debugging was done in loader.conf, using
individual strings, one per boot:

debug.acpi.disabled="KBD RTC TIMR VGA"
debug.acpi.disabled="KBD RTC TIMR VGA_ GP17 GPP0 SWUS SWDS"
debug.acpi.disabled="KBD RTC TIMR VGA_"
debug.acpi.disabled="KBD RTC TIMR VGA_ GPIO HPET TPM_ GED_ WDAT AMDI"
debug.acpi.disabled="KBD RTC TIMR VGA_ TPM2 WDAT HPET"
debug.acpi.disabled="KBD RTC VGA_"
debug.acpi.disabled="KBD RTC TIMR VGA_ ged GPIO TPM2"
debug.acpi.disabled="KBD RTC HPET TPM2"
