How to activate/enable Redis for a user from the command line

As per title. There must be a way to toggle this switch on https://yourdirectadmin.com:2222/user/redis using the command line. I know it has something to do with CMD_REDIS, but I'm stuck on how to execute it programmatically.

Not to be confused with REDIS=ON in the user.conf file. This is already set and enabled in the user packages.
