Rear Drum to Disc Conversion Question

I'm sure this has been answered, but it was hard to find a specific answer by searching the forums. Thank you for responding if you're able to.

I'm converting to disc brakes. The kit says I need to regularly use the parking brake to adjust the rear caliper. My plan was not to hook up the E brake. Is there a way to adjust the rears permanently without hooking up the E brake, or is it easier to just hook up the E brake?
