Below is just a simple example for illustration.

Example

from kivy.app import App
from kivy.uix.gridlayout import GridLayout


class MyWidget(GridLayout):
    pass


class TestApp(App):
    def build(self):
        return MyWidget()


if __name__ == "__main__":
    TestApp().run()

test.kv

#:kivy 1.10.0

<MyBigButt@Button>:
    text_size: self.size
    font_size: "25sp"
    markup: True

<MyWidget>:
    cols: 1
    MyBigButt:
        text: "Change Other Button Background Normal Property"
        on_release: root.ids.btn2.background_normal = "kivymd_logo.png"
    MyBigButt:
        id: btn2
