Need pkey file to re-apply serial number to bios of domain laptop.

[ZPMMAT]

Very nice laptop that has been sat in a cupboard since i started my job.
HP Pavilion 15 -dk1007na
Would like to get it working for a user, but i am struggling to domain the device correctly due to multiple identifying values being missing from the bios.
Flash update didn't work, so i have downloaded and spent some time learning how to correctly do this via the bios config utility.
Finally got the rest of the syntax for the full commands/config files correct, but i have hit a dead end due to the 'pkey'.
Found little solid guidance on how i can make this .pfx file myself, co-pilot advised that it needs to be made by HP themselves?
So please can i get this key, from there i will be able to make all needed fixes myself and get this device fully enrolled for my user.
Thank you.
