Atmega328P Reset Pin DIrect To Positive Supply

Hi All
Im building a PCB with an Atmega328p running Arduino. The Atmega will be programmed by the distributor and never needs to be reprogrammed. Can I connect the reset pin directly to +5v instead of using a pull up resistor?

Cheers

Yes.

There is also a fuse to disable RESET.

Thanks. Curious if the Atmega can be programmed again after that fuse is set?

Yes. With a High Voltage Programmer.
