Other Trusted Platform Module (TPM) on ITX motherboard?

[1461748123]

Hey guys!
I use BitLocker all the time. In fact, all of my drives are encrypted by BitLocker. Not until recent I realize that all this time when using BitLocker I'm not actually 100% safe since I'm missing a TPM and I just bypass the warning in BitLocker by editing the registry.
I search around a bit and found that ASUS actually make separate TPM modules, but I can't seem to find the connector on my Asus Z370i Strix.
Is it still possible that I can use such a module with an adapter or sort?

After some more digging I found this: http://opentpm.com/
It seemed to be an open source USB TPM module, but I have no idea if it will work or not and this is the only thing I can find that doesn't use a TPM connector...
