How to force update to new version of Safari on macOS Sonoma

Safari 18.0.1 is available for Macs running macOS Sonoma. I have two MacBook Pro's sitting side by side. Both are running macOS Sonoma 14.7. On one, in System Settings > Software Update the update of Safari 18.0 to 18.0.1 appeared in below the option to Upgrade to macOS Sequoia 15.0; on the other, the option to upgrade Safari 18.0, which it is currently running, to 18.0.1 does not appear. Clicking "More info..." only displays information about Sequoia.

I realize that sometimes Apple schedules updates so that demand for them does not exceed server capacity, but I'd like to get this over with and done while I'm still thinking about it. There must be some way around this nuisance.
