What is TPM? What does it do?
TPM 2.0 (Trusted Platform Module 2.0) serves as a hardware security standard utilized to enhance security features in computers and other devices. It acts as a hardware module employed to fortify a computer’s security, supporting key management, encryption, and other security functions.
By securely storing encryption keys and providing hardware-based security, TPM 2.0 augments computer systems with heightened security. This strengthens data integrity and authentication, rendering computer systems more resilient against various cyber threats.

First we will enter the system bios
Then we enter the system security section under the system bios setting.
Then, I go to the system security section under the system bios setting. Then you need to enter the TPM Advanced Settings menu.
We select SHA256 algorithm from the TPM Advanced Settings menu and return to the System Security menu.
