GE Enbrighten Z-Wave Switch - support on/off of indicator LED as action?

Welcome to the community.

Is this the Z-Wave Plus version? Jasco sells this switch branded for Honeywell and for GE.

You can tell if it’s the Plus version by looking at the in, out clusters. Plus version has 0x5E, non-Plus does not.

If it’s the Plus version, Jason Bottjen’s (@JasonJoel’s) driver should do what you want.

I assume you understand how to install user-contributed drivers. If not, details are here:
