如何在mat-select中以编程方式取消选择mat-option，如果它保持在“活动”状态且不可点击

<mat-select [(ngModel)]="selectedOption">
  <mat-option [value]="option" [disabled]="true" [selected]="true">Option 1</mat-option>
  <mat-option [value]="option" [disabled]="true">Option 2</mat-option>
  <mat-option [value]="option" [disabled]="true">Option 3</mat-option>
</mat-select>

import { Component } from '@angular/core';
import { FormControl } from '@angular/forms';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent {
  selectedOption = new FormControl('Option 1');
}

this.selectedOption.setValue(null);
