How to change the font of the SDDM Login Screen?

Now it is this:

  1. When I open the laptop it will use the original font

which the : in 11:16 is aligned at the bottom line

  1. When I unlock the laptop it will use Harmony OS Sans

which the : in 11:17 is aligned at the middle line

And I want it to use Harmony OS Sans when opening the laptop, or whenever I get into SDDM Login screen
