Did you ever get the TPM to work? I don't personally use a TPM with Linux on the XPS 9360, but TPM was tested by our partners when the XPS 9360 was enabled for Ubuntu. > > >> 2.

If you're unwilling to upgrade to a newer userspace, you can write a simple application that can use the new dell-smbios from 4.15 interface to look this up. Most of the work is already done (see https://github.com/torvalds/linux/blob/master/tools/wmi/dell-smbios-example.c#L179) You'll just need to add some parsing around the output (see fwupd code) to tell the version. If you do this, please feel free to submit it platform-x86, it may be useful for someone else in this sample application too. Given you don't have a newer fwupd on your system you won't be able to "easily" flash the newer TPM firmware.
