Might there be a schematic or high-rez pictures available for the motherboard (17N-8L-TGL), perhaps?

I just looked and can't locate it, it might have been lost.

I already checked and updated the bios to the latest version, using the unit's serial number on HP's site. Switching between secure boot enabled or disabled (no option directly called 'legacy') doesn't affect it.

I have a HP 17-cn1007cy laptop that had an unknown bios password. I ordered a replacement bios from eBay and used a rework station to remove the old bios and install the new.
The new BIOS fixed the password problem and the system does boot, but now the laptop will not recognize the SSD at all, in bios or otherwise. I tried installing a cable for the HDD option on the mobo and the bios recognized it, but Windows installation media for both 10 and 11 fail to recognize it to perform an OS install. The system is able to boot to USB media with no issue.
Any ideas on what I did wrong, and...

I am not a robot. I do have a quick question regarding a TV I've just repaired, and I think someone here is likely to be able to help.
