Most efficient way to way to find deep nested object using index path and update it

I have an array of tree structures. I need to be able to find the object using the index paths and update the toggle boolean. I am able to update the toggle using the index path, but this logic will need to be updated if more levels of nodes are added to the tree. How can I make it generic, so my code still works even if the treeData is changed?
It’d be nice if I can set all other nodes false if it is in not in the one of the index paths.

treeData = [{
    name: 'Infiniti',
    toggle: false,
    children: [{
        name: 'G50',
        toggle: false,
        children: [{
            name: 'Pure AWD',
            toggle: false
          },
          {
            name: 'Luxe',
            toggle: false
          },
        ],
      },
      {
        name: 'QX50',
        toggle: false,
        children: [{
            name: 'Pure AWD',
            toggle: false
          },
          {
            name: 'Luxe',
            toggle: false
          },
        ],
      },
    ],
  },
  {
    name: 'BMW',
    toggle: false,
    children: [{
        name: '2 Series',
        toggle: false,
        children: [{
            name: 'Coupé',
            toggle: false
          },
          {
            name: 'Gran Coupé',
            toggle: false
          },
        ],
      },
      {
        name: '3 Series',
        toggle: false,
        children: [{
            name: 'Sedan',
            toggle: false
          },
          {
            name: 'PHEV',
            toggle: false
          },
        ],
      },
    ],
  },
];

indexPathArray = ["0/0/1", "1/0/0"]

for (const index of indexPathArray) {
  const indexArray = index.split('/')
  for (let i = 0; i < indexArray.length; i++) {
    if (i === 0) {
      treeData[indexArray[0]].toggle = true;
    }
    if (i === 1) {
      treeData[indexArray[0]].children[indexArray[1]].toggle = true;
    }
    if (i === 2) {
      treeData[indexArray[0]].children[indexArray[1]].children[indexArray[2]].toggle = true;
    }
  }
}

console.log(treeData);
