I've read:

How to solve "ima: error communicating to tpm chip" messages during boot

and basically, people suggest I make sure my machine's TPM support is enabled.

Well, I certainly don't want to do that! I don't condone its existence and I want the kernel not to try to communicate with it. How can I tell it not to?

Note: I'm using Lubuntu 22.04 LTS, in case this matters. The kernel version is 5.19.0-43-generic.

Unfortunately I do not have the same problem as you so I cannot test my idea to see whether it works, but...

You may be able to fix your problem (in the way that you want to fix it) by blacklisting the appropriate kernel module. First, see if your kernel loads a tpm module and, if yes, find out which tpm module it loads:

lsmod | grep tpm

Then follow the kernel module blacklisting instructions to prevent that particular module from loading, then reboot. But like I said, I do not have the same problem that you have, so I cannot now check whether this works or not. Good luck!
