can i use an integrated amp with my HT receiver?

I am currently using a Pioneer Elite VSX-43TX Receiver which is powering my Paradigm surround set up. This includes monitor 3 fronts, CC370 center, and AMS-150 in-ceiling rear. I also have a Carver CM-1090 integrated amplifier which I am currently not using. This was purchased many years ago, but I can’t bring myself to part with it. It is still one of my favorite components.

My question is:
Is there a way to integrate the carver into my current set-up? If so, will there be any benefit?

I appreciate the feedback..
Thanks
