How to remove config from LTM policy using CLI?

The rules are given an ordinal value when they are added. See below - a single policy with two rules. "rule2" is matched first and "Test-Client2" is matched second. These can be reordered via the GUI or by setting the ordinal value.

root@(B3600-R20-S13)(cfg-sync Standalone)(Active)(/Common)(tmos) list ltm policy Test
ltm policy Test {
    controls { forwarding }
    requires { http }
    rules {
        Test-Client1 {
            actions {
                0 {
                    forward
                    select
                    pool test_pool
                }
            }
            ordinal 2
        }
        rule2 {
            actions {
                0 {
                    log
                    write
                    message test
                }
            }
            ordinal 1
        }
    }
    strategy first-match
}

I can then change this using modify:

root@(B3600-R20-S13)(cfg-sync Standalone)(Active)(/Common)(tmos) modify ltm policy Test rules modify { rule2 { ordinal 3 } }

Which gives me this: root@(B3600-R20-S13)(cfg-sync Standalone)(Active)(/Common)(tmos) list ltm policy Test { controls { forwarding } requires { http } rules { Test-Client1 { actions { 0 { forward select pool test_pool } }

ordinal 2

} rule2 { actions { 0 { log write message test } }

ordinal 3

} } strategy first-match }
