@lritinfra Something to consider also the HPE Intelligent Provisioning is the main way, outside of HPE iLO, HPE SUM or HPE SPP to update the server's hardware firmware. If you aren't using individual RPMs or SCEXE files for the task. With HPE Intelligent Provisioning and HPE SPP being able to update, both firmware and BIOS.
As not all of the updates for firmware will be in a compatible format, for use with HPE iLO. I'm not sure if it has changed but an Administrator Password set on the BIOS (at minimum), also locks out (disables) access to the Erase option on the HPE Intelligent Provisioning. At least it does on my only HPE Server running an up to date BIOS, HPE iLO and HPE Intelligent Provisioning.
Thus disabled HPE Intelligent Provisioning doesn't help with being up to date enough to fix vulnerabilities and bugs at hardware or firmware level.
