The tank cover is two halves, but if you want to reroute cables, you probably want to remove the entire tank, not just the covers. And you can remove the whole thing with the covers still on the tank.
There's two bolts in the back, under the seat, and 1 bolt in the front under the black trim piece.
Remove those, you can then lift the tank a bit at the rear to undo the fuel connector and the fuel pump and fuel lever connector.
There's a black vent hose on the left hand front under the trim piece that you can undo, or just pull out with the tank.
Just look at the routing or take pictures.
And then you can just lift the whole tank of the bike, with the covers still in place.
