To disable specific options in a multiselect dropdown in Ember.js, you can use the disabled attribute in the option tag and bind it to a property in your component or controller. Here's an example of how you can achieve this:

1. Define an array of options with a disabled property in your component or controller:

import Component from '@glimmer/component';

export default class MyComponent extends Component {
  options = [
    { value: 'option1', label: 'Option 1', disabled: false },
    { value: 'option2', label: 'Option 2', disabled: true },
    { value: 'option3', label: 'Option 3', disabled: false },
  ];
}

    <option value={{option.value}} disabled={{option.disabled}}>
      {{option.label}}
    </option>
  {{/each}}
</select>

In this example, the disabled property is used to dynamically enable or disable individual options in the multiselect dropdown based on the value of the disabled property in the options array.
