Is it possible to reset a baseline to be undefined once it has been set?

We were using the baseline here as a filter for the Evertz NATX protocol, and we'd set the Baseline for rows we wanted to monitor and not set it for rows we didn't want to monitor. However, once we've set a row we realized that we could not revert it to be empty again.

I know that filters and conditions are the preferred way to do this, but we were just wondering if this was something that is possible to do?

UPDATE:

For our use case we have several ports on a switch, some of which are expected to be "Up" and some "Down". Since there is no simple filter or condition we can use to divide them, we're using the Baseline to make it simple to filter which is which.

An issue has happened where we have some ports that are occasionally used and we don't need them to be monitored (Otherwise we are getting alarms every time they go up and down that are not useful and just create noise in the system). Previously we would just not set a baseline on these rows and they would be omitted from alarming. But now that the configuration has changed there are some rows we previously marked for alarming that we'd like to remove, but we can't simply delete the baseline.
