Reset HP iLO 5 password (or reset iLO to factory default)

Job ID: 32323194

Budget: $35 – $100 USD

Hi,
We acquired a used HP server that's been wiped before receiving. The server has iLO 5.
I have access to the normal BIOS but are unable to enter the iLO 5. Have tried changing the jumper 1 switch on the main board and tried to follow steps to reset the iLO but it appears to be in 'High Security' mode (ref: https://support.hpe.com/hpesc/public/docDisplay?docId=a00030074en_us&docLocale=en_US).
Need someone whom can advise the way to reset the iLO password or reset all settings back to default. We have serial / console / network access to the server as needed.
I am not able to contact the person who setup the iLO password (otherwise it would be easy).
Please don't bid on this project unless you know the way to resolve and can advise the steps.
