    1) PTT (disable (by default))
    2) Trusted Computing (With the options) :
    • Security Device Support (Enabled (by default))
    • Disable Block Sid (Disabled (by default))
    No securty device found.

    What should I enable for Windows 11 ?

    Intel PTT should be enabled
    What computer is that? Custom build? Laptop? Prebuilt desktop?

    I'm unsure, but I believe PTT (Intel Platform Trust Technology) is to enable the TPM, "Security Device Support" allows the TPM to be visible to the OS, and "Disable Block Sid" should be left at Disabled seemingly.

    Block Sid appears to be an option for self-encrypting drives (NVMe?) that if supported, allows the OS to control whether the drive is unlocked or locked based on if someone is using the computer or not, and presumably involves the TPM. It sounds like the "Disable Block Sid" option disables the Block Sid support (prevents Block Sid and TPM from interacting). If you aren't encrypting drives or intentionally disabled a drive's self-encryption config, this could probably be set to enabled in order to make sure there's no issues (like the OS or TPM going rogue and enabling drive encryption when you aren't expecting it to or something), but I'm unsure as to what situations could occur when Block Sid support doesn't work correctly.
