Is there an MCA way to specify server URI in v5.0?

Background information

What version of Open MPI are you using? (e.g., v4.1.6, v5.0.1, git branch name and hash, etc.)

v5.0.1

Describe how Open MPI was installed (e.g., from a source/distribution tarball, from a git clone, from an operating system distribution package, etc.)

Arch Linux system package

Please describe the system on which you are running

Operating system/version: Arch Linux
Computer hardware: Intel Core i7
Network type: Ethernet

Details of the problem

In v4.1.x the server URI could be set with mpirun --mca pmix_server_uri. The environment variable OMPI_MCA_pmix_server_uri has a similar effect when the process is not launched with mpirun.

In v5.x the server URI is set with mpirun --dvm or prun --dvm-uri. Seems there is no environment variable equivalent for these parameters?
