Multiple instances of D2R

I’m trying to run two (or more) copies of diablo 2 resurrected through lutris. D2R runs a process check for other instances and will only allow one instance at a time unless this specific process is killed.

I am able to do this on windows 10 via “process explorer.”

I can not however use this same well know trick on lutris. At least I don’t now how.

How would I go about running multiple instances of D2R on lutris, knowing that this process is running to prevent multiple instances? How do I kill this process, or at least bypass it?

I searched and saw this same question asked, but no information of a fix.
