If there's no option like 'Always keep on this device' then its possible to temporarily re-enable OneDrive with the 'OneDrive Back up files' option found on the W11 'System' settings page along the top row - but dont' actually start a backup of your files
This logs back into OneDrive and shows a "cloud" OneDrive icon on the bottom right task bar.
It also changed 'One Drive Personal' to '<username> - Personal' on file explorer left panel - maybe this is something new.
There should now be extra OneDrive right-click options available.
To disable OneDrive again right click on that cloud icon bottom right task bar and under Pause Syncing choose 'Quit OneDrive'
If youre happy to use OneDrive and have a large disk space quota then fine, but remember MS now add OneDrive files to Outlook/Hotmail attachments and if you run out of space this might affect email function.
As long as you've made other backup arrangements then think about checking your main document and pictures PC folders arent being synced in the background and even when OneDrive sync is turned off check there arent old files using up OneDrive cloud storage.
