Is there a way to set up Syslog transport in a customer security solution and send it directly to Chronicle?

Syslog settings exist in customer security solutions without configuring Forward. You can configure log transmission right away by entering the Chronicle IP address here.

However, when checking Chronicle Documents, it appears that there is no way to configure a forwarder or receive feed directly if there is no API.

Unfortunately, the solution used by the customer is a security solution developed in South Korea and is not included in the definition provided in the Feed Source type.

However, since it is a Linux-based solution, it is equipped with a transmission function through Rsyslog.

Is there no way??
