Getting rid of buggy ACPI warnings

I have a new cheap mini-PC on which I installed 14.2.  It produces this warning on the console
several tiems a minute:

Firmware Error (ACPI): Could not resolve symbol [\134_SB.PC00.LPCB.ITE8.GETT], AE_NOT_FOUND (20221020/psargs-503)
ACPI Error: Aborting method \134_TZ.TZ00._TMP due to previous error (AE_NOT_FOUND) (20221020/psparse-689)

From poking around, I believe this is due to buggy ACPI firmware, something about a timer that it doesn't support.
Linux users report the same thing, apparently Windows ignores it so the manufacturer doesn't care.
It does not seem to affect the machine's operation.

Is there a way to suppress these messages by telling the acpi driver not to look at whatever this is?
I see lots of settings in the acpi man page but it is not obvious what to turn off.

TIA,
John
