If you set your Apple device to beta updates for the previous release you can suppress the constant prompts to upgrade. Reduces the chance of accidentally upgrading.
It's the same on macOS and iOS, pick "macOS Sequoia Public Beta" or the corresponding release for your device. Apple still pushes security updates for those releases, and I haven't heard of any problems with the kind of minor updates that ship late in a major release's lifecycle, so I think the risk of running this way is low. This kicks the can a year or two down the road, at which point hopefully there are better workarounds.
