I'd like to have a ground plane cover one side of a board as a shield, but still run actual ground connections traces for a star ground. I've tried lowering the rank of the ground polygon, but the wires still get incorporated into the polygon.
Is it possible to have traces running through a polygon of the same net while still remaining separate? I hope this question makes sense😉😉.

The shield plane should not be directly connected to ground. Define the plane as something else,
like a power plane. Then use a component jumper (not a via) to connect it to the audio ground.
Make sure there are no "islands" of shield plane left floating because of the traces cutting it up.

Awesome, thanks a lot guys 🙂. I've used a solder jumper a couple of times, but was hoping for a more elegant solution.
Another option. Pour one big ground plane, and divide the board up into sections by drawing moats with wires in the trestrict or brestrict layers.
Not sure how Eagle works but my software connects the copper pour to a net name which the user can define. If I don't want it connected to a net I just name the copper pour net name "unused"
I always connect copper pours to GND net. This helps protect audio signals from interference.
