Valorant’s anti-cheat system, Vanguard, requires Secure Boot to be enabled. Trusted Platform Module (TPM) and Secure Boot are security technologies that allow Windows 11 launchers to operate at a higher standard of trust and security. To do this, you need to enable these two functions while playing Valorant. This is not only to prevent cheating, but also to prevent unauthorized software from interfering with gameplay.
