InfluxDB 2.0 Retention Policy

Just installed 8.16.0 on a new setup. I noticed that InfluxDB 2.0 was installed. In the configuration database section, the retention policy setup is infinite. I’d like to enter a shorter period, such as 1 month to keep the DB from getting too large. I looked on the influx website and could not find another value to use for a shorter retention period. Is there a value that can be entered to replace infinite with a shorter period such as 1M or 1Month?

I’d like a way to set this option if possible as well.
Most of my grows only last 4-5 months.
After I start a new grow, I have no need to retain any of the previous grow’s data.
I know the DB would take forever to get large enough to fill up the SD card, and I know I can simply delete the DB and start over again with each new grow, but it would be nice to just be able to set it to a retention period of 4-5 months and let it simply delete the old data automatically once it’s past the retention date.
