It's interesting you mention that, because I found it too. However, although it's ticked to be displayed in the menus in Preferences, I can't actually find it in Print Settings! Why would that be?
Aha! https://github.com/Ultimaker/Cura/issues/15505
QuoteThis is a known bug in the last couple of versions of Cura. There is a workaround.
- Disable "Generate Supports"
- In the Mesh Fixes section disable "Remove Empty First Layers"
- Re-enable "Generate Supports"
The setting is improperly hidden when Generate Supports is active.
🙄
The above gave me exactly the preview I wanted.
Unfortunately the resulting GCode upset my printer (Tina2) to the extent that it tried to print the adhesion raft below the level of the bed!
UPDATE: False alarm!
I spent ages looking at the GCode and comparing it with a previous run (without the model's Z offset), and couldn't find any significant differences. So I prepared to re-run the same print file.
By a strange coincidence, the Tina2's z offset calibration had gone awry. I recalibrated it, and the print is now proceeding correctly (apparently).

There is a setting in 'mesh fixes' called 'remove empty first layers' try de-selecting that.
