Is /sys/kernel/security/tpm0/binary_bios_measurements missing also on the NUC?

I have tried the image on a NUC10i7FNB and it worked.

Also, could you look if the tpm has a lockout? Do this and give the output.

sudo snap install tpm2-tools-alexmurray
sudo snap connect tpm2-tools-alexmurray:tpm
sudo tpm2-tools-alexmurray.getcap properties-variable

If it has a lockout from another previously installed OS, then install may fail and install without tpm.

To reset the tpm you have to do

echo 5 | sudo tee /sys/class/tpm/tpm0/ppi/request

Then you have to reboot. You can force reinstall by rebooting with this command:

sudo snap reboot --install

For the Star Labs System's Byte Mk 2, could you give the content of all the /sys/devices/virtual/dmi/id/bios_* ?
