Are HP Pavillion gaming prebuild CPUs PSB vendor locked?

[Monsterfisk]

I recently bought a HP Pavilion Gaming Desktop PC TG01-2000a mostly because of GPU shortages and inflated prices. It seemed like a good deal for a rtx 3600 ti with some pc parts attached.

The thermals are terrible, with the case closed I get right up to nvidia's safety threshold, and the card throttles. (87c on the die, 101.1c on the hotspot. So I've been running it with the side panel open, which keeps the gpu at 85c die/97.5c hotspot. Customer support spent a lot of time on the phone with me, and I believe they were trying to help, but the truth is that it's too many hot components in a case with bad airflow/cooling options, and the whole customer service ordeal was just a very prolonged shrug. 

All that aside though, that's not really surprising, and I'd planned to eventually scavenge the cpu, gpu, nvme and ram for a new system. But today I watched a Linus tech tips video on youtube, where they were talking about 5000 series AMD chips being PSB locked by certain vendors (the example in the video was lenovo.), making the CPU unusable on motherboards from any other manufacturers. My question is: Does anyone know if this is the case for my system? I can't find any info from the retailer or in the manual.

@Monsterfisk,

I don't think that Intel or AMD produces HP or Lenevo downgraded versions of their processors.  It's HP's, Dell's or Lenevo's proprietary motherboards that impose various restrictions, such as not allowing me to overclock my i7-7700K in an HP EliteDesk 800 G3 SFF.

Kind Regards,

No, they actually do. I'ts a hardware fuse that once tripped, makes it unusable on a motherboard where the PSB cryptographic keys don't match. Literally rendering the CPU unusable outside of specific motherboards.

I actually had no idea this existed either, that's why the video got me worried. The chip they 'destroyed' is the exact cpu i got. (ryzen 5600 G) I don't know if this forum likes youtube links, but I'll try:
