You would only have issues if you previously had a TPM that was enabled, and you didn't retain the keys held in the TPM Security Feature. If there wasn't a TPM installed, or it wasn't previously enabled then there wouldn't be an issue. If you do add one, this document will help you to enable it in the OS.       
I have inherited a few R 730XD's and when i was trying to implement bitlocker on one of the VM's ( server 2016), i had the message no TPM found. I have updated the BIOS to the latest version 2.12 and checked in bios and No TPM was found. If the TPM's did not ship in with the servers or were removed, can i purchase them from Dell. Also i have the servers in production. If i plugged in the TPM module, will it be available to the underlying OS running on it . I have Esxi 6.5 installed on it and have a few windows 2016 and linux servers running on it. Thanks
