1. An information handling system comprising:
a management controller configured to provide out-of-band management of the information handling system; and
a network interface controller comprising a network interface controller storage resource;
wherein the management controller is configured to:
receive, from a centralized management platform, information regarding at least one signature associated with a network interface controller operating system (OS) configured to be executed by the network interface controller, wherein the at least one signature is a Secure Boot signature that is operable to allow the network interface controller to install and boot the network interface controller OS;
receive, from the network interface controller, a Dynamic Host Configuration Protocol (DHCP) solicit message that includes a current network interface controller OS version and a hardware architecture identifier for the network interface controller; and
transmit the at least one signature to the network interface controller based on the solicit message to automatically renew the Secure Boot signature via automatic certificate enrollment;
wherein the network interface controller is configured to install the network interface controller OS to the network interface controller storage resource based on the at least one signature; and wherein the network interface controller is a SmartNIC.
