Systems and methods are provided for updating hot-pluggable devices of an information handling system using dynamic EFI System Resource Table (ESRT) entries to implement an ESRT entry update procedure for hot-pluggable devices. Extended configuration space (e.g., such as PCIe Extended Config Space) of a hot-pluggable device may be utilized to store firmware update version information such as firmware version details, which is used in the OS space to update the ESRT table, and the system OS may read and apply the updated firmware version information and apply the firmware update immediately without additional OS reboots.
