Last Modified Date - Display on Modern and Classic site

Hi,

I want to add the "Last Modified Date" as a refiner to my search page - on Classic site.

Currently I get the option to filter as the following  - Screenshot Classic.

And I would like to show it as is in the modern search page - Screenshot Modern.

Any option to configure the Last Modifies Time in the Classic site to be the same as it shown on modern?

Thank you,

Yehuda
