you can ignore the TPM feature through the Ubuntu settings. Just type this command:
echo “blacklist tpm_tis” | sudo tee -a /etc/modprobe.d/tpm_tis.conf
Where the command tee -a will append the echoed line (blacklist tpm_tis) into the end of /etc/modprobe.d/tpm_tis.conf or will create the file if it’s doesn’t exists.
