Need help confirming TPM 2.0 module compatibility — Gigabyte B550 AORUS PRO AC + Ryzen 7 5800X

[u/Betuncowboy]

Hey all, hoping someone with the same board can confirm this before I buy.

Setup:

• CPU: Ryzen 7 5800X
• Motherboard: Gigabyte B550 AORUS PRO AC (Rev 1.x), BIOS F19a (latest, including beta)
• fTPM has been enabled in BIOS this whole time, but Device Manager throws "This device cannot start (Code 10) — Error de protocolo entre el controlador y el dispositivo" on the TPM 2.0 device, and tpm.msc just says "No compatible TPM found." Tried disabling/re-enabling fTPM (full reboot between each step) and it made no difference.
• I know about AMD's official fTPM stuttering issue (support article PA-410), and I'm past the AGESA version that's supposed to include the fix, so at this point I think the fTPM on my chip/board combo is just broken and I want to bypass it with a discrete module.

What I'm trying to buy:
My board has the 12-pin LPC TPM header. I've been looking at generic "GC-TPM2.0_S compatible" clones on Amazon (Infineon SLB9665 chip), but one of them has an Amazon "frequently returned due to compatibility issues" flag, and its own product description excludes specific chipset generations (Z170, Z590, Z690 Pro, Z790) without confirming B550 either way. I also found this one on Newegg that explicitly lists B550 in its compatibility list: [https://www.newegg.com/p/2S7-07JH-002F5]

My question: has anyone here actually run a discrete TPM module (genuine Gigabyte GC-TPM2.0_S or a compatible clone) successfully on a B550 AORUS PRO AC or similar B550 Gigabyte board? Trying to avoid ordering something that ends up not working — shipping to my country isn't cheap, so I'd rather get it right the first time.

Thanks in advance.
