Ionic ion-datetime presentation="date" styling

Hi everyone, I want to change font-size of calendar-day element and border-radius for active element of ion-datetime.
These elements are part of the shadow DOM and ionic documentation has shadow parts to help style some of them.

For datetime there is such part

wheel-item - The individual items when using a wheel style layout, or in the month/year picker when using a grid style layout.

It worked only for wheel type for me though the documentation implies that there should be some customization as well.
Checked this both on Vue and Angular version of Ionic

Is there a way to style calendar items?

Not at the moment, but we have an open feature request: feat: datetime, expose calendar grid buttons for styling · Issue #25340 · ionic-team/ionic-framework · GitHub
