My system is: Roon server running on PC - lan - Sonore UltraRendu - USB - DAC.
Can I install Dirac Live Room Correction Suite on the PC and still use same topology including the UltraRendu?
No, probably not. On your Roon Server, it outputs internally to Dirac or externally via LAN to the UltraRendu. One or the other but not both.

Dirac live on the PC is for its local output only via the pcs soundcard or USB to a connected DAC. You cannot use it to send a stream to another device over the network. You will need to use Roons DSP for that.
You can also just use a Dirac-capable amp or AVR downstream of the DAC. Tune that with DIRAC. I have a Denon AVR that I’ve done this with and feed Roon via a Nucleus w/HDMI out.
