[NAME]   that is incorrect about TPM The XPS 8700 does not have 1.2 TPM or TPM hardware. It has INTEL PTT in bios.   Some Dell systems do not ship with a TPM(Trusted Platform Module) module, and instead, use PTT (Platform Trust Technology). PTT is a lower-cost solution that supports the same functions of the TPM 2.0 [URL] [URL] The Trusted Platform Module should show under Security devices in Device Manager.  8700 has PTT and UEFI CLASS 2.3.1 secure boot ability. There is No option for TPM in BIOS Setting, which is under security, only INTEL PTT There should be a setting for this in F2 BiOS. Intel PTT is basically the firmware (bios) alternative to a the hardware based TPM. Intel PTT works on pretty much every processor/chipset since 4th Gen Core (Haswell) processors were introduced and it even supports Bitlocker. This is because Intel PTT supports all Microsoft requirements for firmware Trusted Platform Module (fTPM) 2.0 [URL]  
I have an XPS 8700 and it is running well with Windows 10 but I don't think it has a TPM chip. TPM 2.0 is going to be required by Windows 11. Is it possible to add a TPM chip to an XPS 8700? Thanks
XPS 8700, possible to add a TPM?
