How can I tell if the CPU I get is from a Lenovo PC (PSB locked)?

I have the EliteDesk 805 G8 variant of the Elite Mini 805 before HP rebagged it as the Elite Mini, then back to the EliteDesk, but under the EliteDesk 8 G1a or G1i label. The EliteDesk version is functionally the same except for the nameplate, BIOS name, and 2.5" caddy, which the Elite Mini does not have or need unless you run dual NVMes. However, mine has the Ryzen 3 5350GE APU, but the price matched. I want to see about putting a Ryzen 5 5650GE in the machine, being the rest is good (16/512), but the CPU is the weak spot -- okay, it's a quad-core chip which blows away every low-tier chip before Ryzen 3000 with 4000 being similar, but the 5 is a six-core part. The issue is that Lenovo PSB locks their CPUs, so I can't use a Lenovo pulled CPU in my HP :-(. NOBODY MENTIONS THE ISSUE UPFRONT WHEN I LOOK!

I am trying to find a way to check this before I buy the CPU (I know sometimes ratty systems come up with the "right CPU" under the ProDesk series, but usually the CPU is easier to get then a crappy cosmetic ProDesk, or from a parts unit with a persistent BIOS password that can't be cleared being on the SureStart memory vs CMOS RAM), but none if the sellers of bare CPUs mention if it came from a Lenovo - this is compounded by the searches I do for it pulling up the locked Lenovo PCs mixed with the CPU I want, and I know I can't reuse a locked Lenovo CPU to the degree I need to treat the installed CPU as PSB locked because the odds of it being "usable" is extremely low.

Is there some code unique to the AMD OEM CPUs that ONLY shows up on those I can use as a filter, or will I just need to roll the dice and pray it isn't locked, or upgrade a cheap 16/256 unit with the Ryzen 5 to 16/512?
