It's possible to disable TPM with the tpm_clear command from the tpm-tools package which may need to be installed if it's not present in the filesystem.
If the command: lsmod, outputs any tpm modules, it's those modules that can be blacklisted to shut down tpm. There may however, not be be any modules with "tpm" in their name. In viewing the module output in the log posted in post #13, I can't identify any tpm modules loaded, so blacklisting may not be effective. Better eyes than mine may see more.
In the output from the pastebin link in post #25, the tracker-miner-fs program is failing. It's not an essential program and can be disabled with systemd or safely removed with apt. I can't say if it's involved in freezes.
It's questionable that disabling swap will help the system.
Perhaps after removing snaps, clearing tpm or disabling tpm, removing tracker-miner-fs, enabling swap (if disabled) you could report on the freeze situation.
If the package: firmware-misc-nonfree, is not installed for the i915 graphics driver, that package ought to be installed since it includes significant i915 blobs.
