is it possible to bring minimalist cards to use and mix with my old dashboard?

[p2544]

It seem that I need to use studio code to create all the button.
I just want to know is it possible to do it in normal / default dashboard environment, because
I have a existing old dashboard full with lovelace cards, I just need some minimalist to use with.
and I didn't want to recreate all again.

If yes, kindly advise how.
