According to the specifications, the HP Z440 supports both TPM 1.2 and TPM 2.0. I have upgraded to the latest BIOS version, but my TPM version remains at TPM 1.2. I recalled when I had this same issue on a Dell Precision Workstation that a different tool was needed to switch from TPM 1.2 to TPM 2.0. It appears the HP ecosystem requires a separate step too, but the HP tool doesn't seem to support the Z440.
How do I switch from TPM 1.2 to TPM 2.0 on my HP Z440. I'm running Windows 10, but happy to switch to Linux if needed.

download the desired TPM rev 1.2 or 2.0 SP file and run the sp file to extract it, go to the created sp folder
READ the included directions................................................
SLB9660 TPM 1.2 ver. 4.43.257.0
SLB9665 TPM 2.0 ver. 5.62.3126.0
• Run SoftPaq to extract files. By default it will extract the files in
• Open CMD Prompt in Administrator mode and run TPM.MSC to determine the TPM
o Manufacturer Name: IFX
o For TPM 1.2, Manufacturer Version: Either 6.40 or 6.41 or 6.43
o For TPM 2.0, Manufacturer Version: Either 7.40 or 7.41 or 7.60 or 7.61 or 7.62 or
o Specification version: Either 1.2 or 2.0
• The utility supports
o Graphical User Interface (GUI) for step-by-step execution
o Command line mode (including silent execution)
• Run MSINFO32 to determine 32-bit or 64-bit OS. Examine System Type (will show
either “x64-based PC” or “32-based PC”).
• Run the appropriate utility (TPMConfig.exe for 32-bit OS or TPMConfig64.exe for
64-bit OS) as an Administrator from the folder where the utility and TPM FW BIN
file are located.
• An encrypted password file generated by the HpqPswd.exe utility and supplied with
the –p command line option to provide the Setup Password, if set.
• The file will be renamed as “TPM.pwd” and will be copied to the EFI partition along
with the TPM image file, and read by the BIOS. If incorrect, the update will fail. If
not provided, the BIOS will prompt for the password.
• AES 256 encryption: as of version 184.108.40.206, if a password file with improved
encryption is supplied, it will be converted to legacy encryption for BIOS
compatibility when copied to the EFI partition.
• Online flash: Not support. The user will not be prompted.
TMP firmware binary
• TMP firmware binary to be updated, by default, is expecting to be located on the
same folder with the tool; unless command line switch “f” is using to specify the
firmware to be updated.
• On Windows 7, TPM 1.2 must be activated in BIOS (Check TPM state in BIOS).
• On Windows 8.x or Windows 10, the OS will automatically take ownership of TPM.
• Windows 8.x and Windows 10 require GPT partition style when using TPM 2.0. The
BIOS setting for boot mode should be set to native UEFI (recommended) or UEFI
• Windows 7-64, Windows 8.x, and Windows 10 will work with MBR or GPT partition
style when using TPM 1.2.
Required Supported Files
• Currently supported SoftPaqs containing the firmware binary files: SP81900 and
