Slooowww Boot - All Typical Fixes Done

I've got an HP Spectre x360 from 2017 that is healthy in all other respects. I upgraded "manually" to Win11 years back and just recently upgraded to 24H2. The laptop has TPM 2.0, but has a proc that is just outside of MS specs. Still, Win11 runs reliably and rather snappy. The problem is that on boot, after the HP logo/BIOS boot, Windows takes about 30 seconds to show the logon page. Then, it can take a while to open to the desktop. It has never been anywhere near this slow in the years I've owned this machine.

I know that I can go back to the previous version of Win11, but I'd like to try to work this out if I can. I've done all of the typical "fixes" from disabling FastBoot, to limiting startup programs and more - all the stuff that routine YouTube videos cover. With FastBoot enabled, it's faster for sure, but my keyboard drivers don't seem to be loading and I have no access to the keyboard.

So, are there any fixes, hacks, etc., that you would recommend?
TIA!
