Is there a parameter for "extruder enabled" that can be read in the start/end G-code?

As the title says. Haven't been able to find any answers through Google.

No.

After carefully parsing through @nallath 's answer (and then taking a moment to look around) it appears that like many other things in Gcode, there is no way to do a query.

 

M590 is listed on the Reprap Wiki site but it doesn't appear to be supported by any firmware (except maybe Klipper).

Some firmware has the ability to interpret if statements in g-code, so i guess that is what zhutwo is looking for. But the cura parameters that you can put in the g-code are limited to settings only.

Yes, it would be an if statement to check if an extruder is enabled before setting its temp. Enabling/disabling an extruder in Cura is kind of a setting, so I was hoping it would be a thing.
