Get rid of TPM message?

[rayandrews]

Upgrade to bookworm gives me a new message on booting that I never saw with bullseye:

"Error communicating with TPM chip"

I don't think my ancient machine even has a TPM chip. There's no problems, bookworm boots just fine, but if possible I'd like to disable even the attempt to look for the TPM chip -- it will save some pointless journal entries and maybe save a microsecond.

Can you report a complete excerpt about the message from your system logs ?

A quick search lead me here:

Hope this helps.

Yeah, I found that one too. Alas my BIOS has nothing like that. So that's why I'm hoping I can just convince the kernel to not bother looking. Pretty trivial issue tho, I'm not going to loose sleep over it.
