Enabling tmpfs causes security warning in Security Advisor

[nougad]

Running the Security Advisor creates a medium warning:

Attackers may install malicious startup scripts to execute/install malicious programs.

The following custom startup script(s) were found on your system: /usr/local/etc/rc.d/openHAB-tmpfs.sh(Unknown Package). These scripts may have been installed by a malicious program. If you do not recognize these scripts, please contact Synology support for help.

When clicking fix it comments out the whole script

Is there any way to tell DSM this is a valid start script? I don't see an option to ignore this one script. There is only a option to ignore malicious scripts in general.
