No Need. All that will be set as required during the pre flight set up for the next sector. Having said that if your offsider does it, I wouldn't loose too much sleep, I imagine around 20 percent of guys switch off FD's, etc after landing. The FCOM is pretty clear, it's also stated in the QRH however if you take the QRH too seriously you're not allowed to put your tray table away until you've got a line up clearance, etc...
