How to set date format to DD.MM.YYYY and time format to HH:MM:SS (24 hours) in admin area?

3.90

I want to change date and time formats in admin side.

Now it shows like: 12/30/2023 12:16:24 AM

I want it to be like: 30.12.2023 00:16:24

On my VPS it displays the date and time correctly. I have IIS there and all its settings.
In my admin my language culture is ru-RU

How can I do it?

Thanks in advance.
