Ever since my purchase (In June 2022), my 2022 Zephyrus GA503RM (Laptop) has been experiencing a system-wide stutter. I found some threads and an official post from AMD that it's being caused by ftpm. I have decided I would like to disable TPM until a fix. However, my UEFI setup doesn't have an option for disabling TPM, switching to discrete, or anything else relating to TPM. I see the option to disable secure boot but that won't do it, will it? So, how can I disable it?

I know Win11 requires TPM but that during the installation of both Win10 and Win11, you can disable the TPM requirement. However, the instructions don't indicate that TPM won't be used, just that it won't be required if you do a registry edit during install. I'm also aware that you might not get Win11 updates if you don't have TPM.

I still want to disable it. I will downgrade to Win10 if I have to. How can I stop Windows from using TPM at all without having to disable it in BIOS? I tried opening tpm.msc (In Win11 as I haven't downgraded to 10 yet) and looked for a disable or stop option but only found the option to "Clear TPM."

If I am not mistaken, to enable BitLocker and store your encryption key within the fTPM, you have enabled to Secure Boot. A byproduct of disabling Secure Boot when you are not otherwise using the TPM will be that the TPM will be available but essentially unused. I don't know if clearing your TPM, if it currently is unused, will prevent stuttering. I would absolutely, NOT CLEAR THE TPM, if you are using BitLocker.

I know Win11 requires TPM, but during the installation of both Win10 and Win11, you can disable the TPM requirement.

You can disable the requirement it does not actually disable TPM within Windows. The article you linked to indicates the stuttering can happen on unpatched devices that are running Windows 10 and Windows 11. All that means is that downgrading to Windows 10 will not resolve your stuttering problem.

However, AMD released an AGESA microcode update that resolved the stuttering in June 2022, and ASUS released a firmware update that included that microcode update back in September 2022. If you cannot disable the TPM, which is a real possibility, I would simply update the firmware on your machine.
