bcdedit.exe -set TESTSIGNING ON - Access Denied

[DKS]

"The boot configuration data store could not be opened.
Access is denied."

WTF does any of this mean?!

I'm trying to install drivers for a USB to OBDII interface. It won't let me install the drivers for it until this step is done apparently.

Any advice welcomed!

Sorry it's Win 10 on a HP laptop.
I'm the admin on this laptop.

Thank you for your reply.
Running it in admin returns:

"An error has occurred setting the element data. The value is protected by Secure Boot policy and cannot be modified or deleted."

Thank you.

No change
What's the UEFI option please?
