How to keep bool true even when other method try to set it off

Hi, i'm fairly new with coding and right now i'm making a game mode selector.

The problem is that I have two methods with fairly similar cases and this is what should happen:

when I click a button, it should activate the Firstmethod that contains bools for gameobjects. And when I click another button, it should activate the SecondMethod with similar aspects. When I click either button again, it only deactivates gameobjects that are not in the other method.

now the problem is that when the SecondMethod is deactivated, it also deactivates the FirstMethods gameObjects that are in the SecondMethod

Ex.

public void FirstMethod(bool isOn) { gameObject1.setActive(isOn) gameObject2.SetActive(isOn) }

public void SecondMethod(bool isOn) { gameObject1.SetActive(isOn) gameObject3.SetActive(isOn) }

If done like this, the gameObject1 in the FirstMethod will be deactivated aswell. Is there any good way to check if the FirstMethod has the same gameobject active and when the SecondMethod is being deactivated it wouldn't set the gameObject1 off?
