Hello Lemon pie,
1.5mm is very low action.

If your bridge is as low as it can go the only thing you can do is to try and adjust is the neck's truss rod.

You can try moving the neck back (tightening the nut by turning it to the right as you look down the neck from the head stock). You do not have to make a lot of movement, only a few degrees at a time and be very careful not to apply too much torque, don't force it.

Be aware that you may also cause problems at the top of the fret board. The clearance there may drop too low and cause buzzing.

Or...was it the other way around?

Truss Rod is not problem
Neck is straight

I understand that, but you are not adjusting it to be straight but to lower the action at the 12th fret.It costs nothing to try it, but this might also cause buzzing.
There is no other easy way to reduce the action unless you are willing to search for an alternative hardware solution.

The important thing is the guitar's playability, not some arbitrary measurement.The SG is a G scale and the Parker is an F scale guitar.
You are talking about a very small change in action height. I would think that you would be able to easily accommodate the difference without difficulty. Making drastic changes to this guitar would be a mistake.
