HP Wolf Security Zbook G9 laptop

I have a bootable USB stick that contains the try bootable image of Ubuntu 22.04.2 LTS as distributed by Ubuntu. Normally, after the try, I do a full install as the try verifies that Ubuntu can "see" the hardware. On an HP Zbook G9, following the HP service manual, I removed the HP supplied MS Win unbooted SSD, and replaced it with a new unformatted Crucial SSD. The G9 has "Wolf Security". There is no menu to boot from the USB drive and there is mechanism to boot and eliminate Wolf Security from the machine. Do I need to first boot into the supplied MS Win SSD, make changes in the BIOS, and then try to boot the USB stick with 22.04.2 ? Will it boot? What changes must be made? If I dd as root from a working USB based Ubuntu system with a UEFI secure boot to the unused SSD (accessed via a USB to SSD external attachment device) will that work? Say that the working system is /dev/sda and the USB attached SSD appears as /dev/sdd, then I would do a full dd from /dev/sda to /dev/sdb that should include all of the partitions including UEFI boot (or is even more required?). If a "key" is required to boot, how does one discover the magic key? Any information would be helpful.

In the USA, HP provides a toll-free (no charge) telephone number to Technical Support (TS). On the bottom of the machine in low contrast small print is a serial number. Once that was provided, the TS person walked me through the procedure. Note that I already had downloaded the HP service and repair manual for this machine, had removed and stored the 1 TByte SSD that contains the HP installed MS Windows 11 environment, and installed a new Crucial 4 Tbyte SSD. For those who may find a URL on the web showing the procedure used to open the machine and change components (the various locations, etc., are correct in the video) beware: the person doing the disassembly was not using a grounded antistatic mat nor was she/he wearing a grounded wrist strap. I use these things plus antistatic tools where the entire assembly is grounded to the building mains ground (earth). After HP TS walked me through the procedure to access a USB memory stick (thumb drive) boot, upon which Startup Disk Creator has installed the "stock" 22.04.2 ISO image, the USB memory stick booted (with the HP Wolf Security splash screen being displayed prior to boot) and the try to verify hardware support and then the install completed without issues (I am using the HP Zbook G9 to post this). Two comments: the G9 is certified for 20.04 but 22.04.2 works fine; supposedly, the (proprietary) Nvidia package has issues on these machines under 22.04 (the HP TS person provided me with HP document). I installed the Nvidia package (the one that had tested listed for the package) and it is working without issue. I need the full functionality of the Nvidia driver and configuration tools.
