Edit “more info pop-up”

is possible edit this? what is the name of the view?

Not really. What do you want to do?

It’s called a “more info pop-up”.

What comes to mind. For exemple add plot of sensors or add other toggles for the peripherals

Your best bet is to replace it with your own custom designed pop-up card using browser-mod https://github.com/thomasloven/hass-browser_mod#popup

No, you can still do it in raw edit mode.
