How to enable custom script on AiMesh nodes?

RT-AC86U, Merlin 386.1_2.

I want to enable custom scripts on AiMesh nodes. But when I put the node IP in web browser and login, it automatically redirects to the main router portal. In the node's log, I found the following, even though the main router has custom script enabled, which indicate this setting is not replicated to AiMesh nodes automatically.
admin@RT-AC86U-76C8:/jffs/scripts# grep services-start /tmp/syslog.log*
/tmp/syslog.log:May 5 00:05:14 custom_script: Found services-start, but custom script execution is disabled!
/tmp/syslog.log:May 5 00:05:14 custom_script: Found services-start, but custom script execution is disabled!
/tmp/syslog.log:May 5 00:05:14 custom_script: Found services-start, but custom script execution is disabled!
/tmp/syslog.log:May 5 00:05:14 custom_script: Found services-start, but custom script execution is disabled!
admin@RT-AC86U-76C8:/jffs/scripts#

How may I enable custom script on AiMesh node? Do I have to remove it from AiMesh, enable custom script and add it back in? Or is there an easier way(like, from CLI)? Thanks!
