How to remove beta software status? iMac 2015 with Monterrey

Hello, in trying to resolve another issue (printer driver), I was advised that my machine has a beta version of Monterrey, 12.7.5, installed, I do not recall how I managed to select beta software, but I want to revert to a released version. I found an online "how-to" but the steps did not match what appeared in the dialog boxes in machine/software settings, and now I'm being prompted to install a "12.7 Seed 5". Seems I've managed to go the direction opposite what I wanted to accomplish.

Can someone please point me to a hopefully straightforward, step-at-a-time means for getting back to the last "released" version of Monterrey, I presume 12.7.4? Thanks in advance!
