Second Redis instance?

Hi.

I've redis-6.2.13 installed and running.

I need to run a second Redis instance with a different .conf file.

For instance, under FreeBSD, this is as easy as adding in rc.conf file;

redis_profiles="foo bar"

Giving opportunity to use /usr/local/etc/redis-FOO.conf
/usr/local/etc/redis-BAR.conf respectively, as separate instances.

How can I do the same under OpenBSD 7.4?

Any help, ideas, tips & tricks would be appreciated,
Kindest regards.

Mark.
