The default tooltip parameter is not available in .NET MAUI, and I'm unable to find anything in the docs.

Unfortunately, support for features that only make sense on platforms with a mouse, has not yet been added to Maui. (Tooltip requires Hover, which does not generally exist on a mobile platform.)
I personally don't expect to see this in first Maui release.
Add your interest as an upvote or a comment on github maui issue - feature request - tooltip.
Check there in a few months to see if there is any mention of adding it to roadmap, or to planned features.
Also pay attention to maui - proposal - mouse moving over control. That is the more general category. Unfortunately, there are no comments by devs on that - maybe search to see if there is any similar proposal.
