在LWC中选择了radio/check时如何禁用选项？

<template>
  <lightning-radio-group name="options" label="Options" onchange={handleChange}>
    <lightning-radio-group-item label="Option 1" value="option1" disabled={isOptionDisabled}></lightning-radio-group-item>
    <lightning-radio-group-item label="Option 2" value="option2" disabled={isOptionDisabled}></lightning-radio-group-item>
    <lightning-radio-group-item label="Option 3" value="option3" disabled={isOptionDisabled}></lightning-radio-group-item>
  </lightning-radio-group>
</template>

import { LightningElement, track } from 'lwc';

export default class MyComponent extends LightningElement {
  @track isOptionDisabled = false;

  handleChange(event) {
    // Handle radio/check change event
  }
}
