How to put rear calipers into service mode without a tool on a 2018 Civic?

[Donald60]

I'm planning to replace the brake pads and rotors on my 2018 Honda Civic for the first time this weekend, and I've watched several tutorials, but I'm still unsure about a couple of specifics. I'm concerned about properly retracting the electronic parking brake caliper piston on the rear wheels since it's not the traditional screw-in type, and I want to make sure I don't damage the system. For DIYers who have tackled this on similar models, what was your process for putting the rear calipers into service mode without a professional scan tool, and are there any torque specs or bedding-in procedures you found critical for avoiding noise and ensuring even wear?
