Can I transfer an EFI (serial included) without cloning the drive?

I installed Hackintosh on two SSDs. I wanted to do a test run before wiping my Window’s installation.

I got iMessage to work on SSD1. I must’ve messed up somewhere, and I can’t get iMessage to activate on SSD2. Can I wipe my SSD2 and transfer the working EFI from SSD1 to SSD2? I do not have a way of plugging them both in at once.
