XR2 Remote with HDMI DTA - XFinity

I'm trying to set up an XR2 remote to control just the power on the TV, but leave the volume controlled by the DTA. Is this possible?

My small amp the powers the speakers has a dial for the volume, so I'd like to control the volume with the remote.

Thanks for any ideas!
