Can Z840 update from TPM 1.2 to 2?

[kaarth]

Hi, A game I have been playing now wants users to have Secure boot and TPM 2.0 to use its new servers, I have enabled secure boot but am having trouble with getting TPM to update and not sure if I am missing a step or if it cant be done on my device which is a Z840.

Tried googling and got a range of answers but couldn't find a solution.

I have secure boot enabled but TPM shows as 1.2 when checking windows or in the BIOS

I have run the HP support assistant twice to check for updates and it updated my Bios and now shows everything up to  date but I still cant figure out if or how I can get TPM to update or if I cant update 

Specs from system tool: 

Windows 11 - Version 10.0.22621 Build 22621
Processor- Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz
BIOS Version/Date - Hewlett-Packard M60 v02.58, 7/12/2021

Motherboard I believe is a hp 2129

Hi:

Yes, it can be done.

Please see this discussion:  The Z440 uses the same files and procedure.
