The initial setup is not a wrist hinge. It is just the shaft in line with the front arm* and the back wrist bent inward to help hold that shape. This is also how the shaft and wrists should look later on in the swing, moving through impact, for a solid golf shot. You don’t bend or hinge your wrists to get into this position. You just take your grip with the shaft in line.
Yes, you just maintain the initial setup position in the backswing and back down through impact and it will eventually release on it’s own after impact.
* The shaft in line with the front arm, should create a flat front wrist. This may even increase to bowed out due to dynamics of the downswing.
