Answer 1

Solution by @Eliseo:

If you want not loose the validate you can use [attr.disabled]="condition ? true : null" (or any condition). This give your control an apparence of disabled but still is "validating".

Answer 2

The reason disabled fields are not validated is because angular forms skips them from the validation. Since the control level is skipped, you will need to add that validation on the group level. credit goes to this comment https://github.com/angular/angular/issues/25182#issuecomment-408629027

The code would look like this:

this.formGroup.setValidators((form) => Validators.required(form.get('disabledControl'));
