Linux kernel disables default TPM bus encryption for performance

Developers of the Linux kernel have disabled TPM bus encryption by default in recent updates to address performance issues. This change, introduced after features in Linux 6.10, prioritizes efficiency over security in many use cases. The decision reflects community feedback on balancing protection against slowdowns in TPM-dependent operations.
