FreeBSD 12.2-RELEASE-p9 trim: open failed: /dev/ada0: Operation not permitted

freebsd-questions:

I have a computer with FreeBSD:

2021-08-29 19:14:07 toor at f1 ~
# freebsd-version ; uname -a
12.2-RELEASE-p9
FreeBSD f1.tracy.holgerdanske.com 12.2-RELEASE-p7 FreeBSD 
12.2-RELEASE-p7 GENERIC  amd64


The system disk is an SSD:

2021-08-29 19:18:53 toor at f1 ~
# camcontrol devlist | grep ada0
<INTEL SSDSC2CW060A3 400i>         at scbus0 target 0 lun 0 (ada0,pass0)


I would like to trim the SSD, but trim(8) is not happy:

2021-08-29 19:22:36 toor at f1 ~
# trim -f /dev/ada0
trim /dev/ada0 offset 0 length 60022480896
trim: open failed: /dev/ada0: Operation not permitted


Suggestions?
