How to change worm:grace_period in TrueNAS scale?

TrueNAS General
,
1

TrueNAS-24.04.2
It has WORM enabled SMB share.
In “Advanced” section “Additional Parameters String” worm:grace_period = 300

But I can’t change it to another number. It’s not implemented in GUI.

Also I found that /etc/smb4.conf is has only [global] section with a few records.

testparm -s display wide info about server and shares. And it show worm:grace_period = 300 too.

But how can I change worm:grace_period for share permanently?
