Linux Kernel Configuration
└─>Security options
└─>TPM-based trusted keys
In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
Enable use of the Trusted Platform Module (TPM) as trusted key
backend. Trusted keys are random number symmetric keys,
which will be generated and RSA-sealed by the TPM.
The TPM only unseals the keys, if the boot PCRs and other
criteria match.
