How to stop disabled Google Assistant popping up on home button long presses?

I don't use Google Assistant, so I disabled it, by (1) opening the Google app, then (2) going to settings from the profile icon, then (3) choosing "Google Assistant" settings, then (4) scrolling a long way down to "General" settings, then (5) toggling off the top toggle that simply says "Google Assistant". However, sometimes the device thinks I long-pressed the home button (e.g. if I swipe up too slowly) and pops up a Google Assistant nag screen asking me to re-enable it. How do I stop the Home button from doing this? There don't seem to be any related settings in the Google app settings. I've found dozens and dozens of articles explaining how to disable Google Assistant - which I've already done - but not how to stop this home button behaviour. Device is a Samsung S22 Ultra running Android 14 and OneUI 6.0 if that's relevant.
