How to flatten a nested forEach?

I have the following input:

 schema: [{
    fields: [{
      name: 'name',
      type: 'text',
      col: 10,
      value: ''
    }, {
      name: 'description',
      type: 'text',
      col: 2,
      value: ''
    }]
  }, {
    fields: [{
      name: 'password',
      type: 'text',
      col: 8,
      value: ''
    }, {
      name: 'confirmPassword',
      type: 'textarea',
      col: 4,
      value: ''
    }]
  }],

And I set the values of the objects of the nested arrays like this:

updateField (name, value) {
  this.schema.forEach((formGroup, index) => {
    formGroup.fields.forEach(field => {
      if (field.name === name) field.value = value
    })
  })
},

Is there a way to avoid using two nested forEach? (Without using any library like Lodash?)
