Custom editors is the only built-in way to do this.

Say you have something looking like this:

 public class MyBehaviour : MonoBehaviour {
     
     public bool myBool;
     public int myInt;
 }

And you only want to show the myInt in the inspector if myBool is true.

To do that, create a custom inspector:

 using UnityEditor;

 [CustomEditor(typeof(MyBehaviour))]
 public class MyBehaviourEditor : Editor {

     public override void OnInspectorGUI() {
         //The target variable is the selected MyBehaviour.
         MyBehaviour mb = (MyBehaviour) target; 

         //Create a toggle for the bool variable.
         mb.myBool = EditorGUILayout.Toggle("MyBool", mb.myBool); 

         //Create an input field for the int only if the bool field is true.
         if(mb.myBool) {
             mb.myInt = EditorGUILayout.IntField("MyInt", mb.myInt);
         }
     }
 }


Remember to put the editor class in the Editor folder, otherwise the UnityEditor namespace won't be found.
