Program for throwing out in-the-ins (Dark Souls 3)

All the sleds. I want to go with my friend DS3 in the coop, and the only problem that does not give normal play together - it's inalresms. We don't want to pPM, we are only interested in SEE content. If you can just go offline in a solo, alas, you can't do that in a coop.
I've heard that there are programs for throwing out players connected to the host. Unfortunately, I couldn't find one. I decided to ask, maybe here who will tell, what prog called and where it can be found? Thank you in advance.
