This is a X->Y problem. Here is a solution for X:

Bit 3 of high fuse of the ATmega328p controls if EEPROM memory is preserved through the chip erase. You can change the high fuse setting in boards.txt. Restart the IDE to apply the new setting.

The fuses are written when you select the "burn bootloader" option in the Arduino IDE.
