One option is to run MongoDB in Docker containers. That way, you can have two separate installations of MongoDB, with different versions, and you can guarantee that they won't conflict with each other in any way.

There are images available for several of the more recent versions of MongoDB on dockerhub, or you can build your own docker image - for example if you need to use MongoDB Enterprise.
